2-pt Conundrum

Submitted by M Ascending on October 3rd, 2022 at 11:40 AM

I'm surprised to have seen no discussion of what I believe was a tactical error by Harbaugh -- failing to go for a 2-pt. conversion twice when "the Book" calls for it.  When we scored in the 3rd quarter to go up 19-0, the book calls for a 2-pt. Conversion to try and go up 21-0. Similarly,  when we scored to make it 26-7, the book would again call for a 2-pt. Conversion to go up by 21.

In both cases the theory is to protect against the most immediate threat. ie., Iowa scoring 3 td's as opposed to 2 td's and 2 fg's. I've seen Harbaugh go for the 2 points in the past in similar situations.  Thoughts on his failure to do so twice in Saturday?  How did you feel when Iowa was driving and the score was 20-7?

I agree with this.  Going for 2 in the 3rd has inherent risk given the amount of time left in the game and the variables that presents. Having a certain point (Hello Jake Moody!) is a solid choice.   I would guess that Harbaugh didn't go for two in the 4th simply to avoid giving appearance of running up the score.  There was no way THAT Iowa offense would score 3 TD's in the waning moment of the game.

And in this case, not running up the score also emphasized the belief that there was no way in holy hell that Iowa was coming back. A lovely case of having your cake and munching on it. . . across the sideline. Harbaugh's shit-eating grin; Ferentz's scowl; a nice pairing with fava beans and a good chianti.

Harbaugh, and Michigan football in general, tend to approach the game scientifically. I haven’t seen “the book“, but I have heard the coaches refer to their decision-making based on objective criteria.  I don’t know if “the book” says what you think it says at that point in the game with that score differential, but to answer your second question, I was feeling fine from start to finish. Michigan was in control of that game throughout.

This has always seemed like a blackjack issue to me — there is a statistically objective answer to this question.  In blackjack it gets put on a card, and I assume it does in football as well.  Assume in football it’s a bit more complex, b/c there is the “time left” issue to consider, which might change things.  But it’s objective, so there doesn’t seem to be much need to have it be a feelingsball moment.  You look at the card and do what it says.  But it seems like it does.  Interested in those closer to coaching for insight here.

I love the black jack analogy, but you’re right, the cards don’t feel or have intuition. 
It’s definitely an EV issue where context matters more the earlier it is considered. 
Middle of the 4th quarter or later, you look at the card and don’t think twice, IMO. 

In Saturday’s game, it definitely felt like the correct call to just kick the PAT. No sense on giving them any chance to get momentum.

The playing cards in Blackjack don't get tired, have injuries, emotions, etc

Exactly. This is always the thing the statisticians and engineers rarely take into account, humans. This is the same reason why computers will never fully replace humans either.

I wouldn't even look at 'the card' until the 4th quarter, and even then I'd be hesitant to follow it with anything more than a 14 point lead.

It only takes one great play by your opponent to change the whole mental state of the game.

I think the go for 2 thing is a bit more straightforward than some situations, but one thing all this statistical game theory stuff absolutely does not account for is momentum or in-game trends.

If you've repeatedly struggled all day on short conversions, that should influence the decision on going for 4th and 2. Or if your kicker looks really shaky that day, or it's windy, that should influence the decision on going for a FG.

We have a dynamic running QB and the best RB in the country plus a whole stable of quality receivers. We should be able to get 3 yards to convert the 2 point try far more than the 50% required to match the EV of a kick. If anything I think we should be going for 2 more often, at minimum every time the statistics say you should or the difference is marginal. 

Everyone always starts with "well if you miss..." but that's a risk-averse, loser mentality. It should be "if you get it, now Iowa needs 14 points just to get to the weighted coinflip of overtime."

It's really hard to get 7 safeties in a quarter and change.

I don't think the Book accounts for the other team having zero points when we scored, and the extra point made it 20. You don't make it, it's 19 - 0

I was happy with that decision to kick the extra point.  First, from a momentum POV, we had it and I can see not wanting to give them anything to celebrate.

Second, from a game perspective, I guess you could claim it was unlikely but if we sit at 19, Iowa could technically tie the game with 2TDS, 2 2pt conversions and 1 FG as opposed to needing 3 TDs.  So I think it was a solid decision (or certainly a defendable decision).

Exactly my thought. At 20-0 the game is essentially over. Just don't give them a sliver of hope. At 27-7 the game was sealed and you don't need to waste a 2-point conversion play by putting it on tape.

I think the last part is the best argument here.  The highly unlikely scenario of IOWA scoring on multiple drives in the time remaining vs. putting something on tape you would prefer to hold on to for later in the season, I have no problem ignoring the "book". Now, change it to OSU, I think I would have a very different answer.

I think either way is defensible. I'll make the case for kicking the extra point there.

Iowa has to get 3 TDs at that point. We're probably figuring we're going to at least kick a FG again at some point. If we get to 23 points, Iowa is going to have to convert two 2-point conversions just to tie.

If we miss a 2-point attempt and kick a FG, they only need to convert one to tie.

 

Edit: Just saw Blue in NC's scenario. Also a good point in favor of the PAT.

My view: 19-0 is a three score difference.  And, if you go for one - to make the score 20-0, it is still a three score game - BUT, it's changes from two TD's and a field goal - to three TD's.

The same would be true at the 26-7 score.  A 20 point lead requires three TD's by your opponent - a 19 point lead is - two TD's with two point conversions, and a field goal?   Which is more difficult for your opponent to overcome?

I have absolutely no issue with the coaching staff's approach - and, kicking the extra point instead of going for two.

When Iowa was driving - and, the score was 20-7, it was still a two score game.  Was I bit anxious, in case a very, very terrible sequence occurred - including "lack of ball security"?   Yes, I was - you know, Kinnick and everything about it.   The good news was - the end result met expectations.

I don’t think he thought much of Iowa hence the vanilla game plan…I’m holding out hope that the good stuff is getting saved for the PSU , state and oHIO

I realize that by "good stuff" you mean explosive plays all over the field - because that's what we'd all love to see.  However, can we just take a moment and appreciate a game plan that eviscerated the #1 defense in the nation with a raw QB making his first ever road start?  I mean, it was executed to perfection!

There is a definite benefit to being up 21 vs. 20, but there is also a benefit to being up 20 vs 19 - and mathematically, you're slightly more likely to fail than succeed.    I think it's defensible either way.

In both cases the theory is to protect against the most immediate threat. ie., Iowa scoring 3 td's as opposed to 2 td's and 2 fg's.

Well, i don't think anyone believed that Iowa would suddenly score 3 touchdowns. Hell, I would have believed Iowa was more likely to score 4 field goals before scoring 2+ touchdowns (meaningless 4th quarter TD not withstanding)

PopeLando

Thought about that too, but there's two considerations here:

1. If you assume that Iowa's offense will take safe FGs on 4th down instead of risking a turnover to go for a TD, making them put together 4 scoring drives is a safer bet for Michigan. 

2. Iowa still has an incredible defense which - though giving up points and yards - was capable of shutting down any given play. So do you run and take the chance that their NFL quality linebackers stuff the run, or do you pass and take the chance that your new starting QB is baited into an interception?

All in all, I'd bet that against a top defense, the Expected Points on a 2 point conversion is less than 1. So you actually come out ahead by kicking the extra point.

The game was functionally over at 20-0.  There was no way Iowa was going to score enough points to threaten using their offense alone.  The only way was to get defensive scores - enabled by fumbles and/or interceptions.

Don't give them more opportunities through meaningless actions like unnecessary 2-pt conversions

I don't care.

In a shootout the question is a bit more pertinent. If we score 6 to go up 19 on OSU in the third, I'm assuming 3 TDs is a genuine threat, and I like the 2-point conversion. But Iowa, while being Iowa, still can expect four possessions or more for the rest of the game; frankly, 2 tds and 2 fgs is a much likelier scenario for them than 3 tds. I like going up by 20 there. (Also, it's a very remote possibility, but a TO on a conversion can be returned for 2 points and that would be a genuinely bad event reducing the lead to 17). 

The score to go up 26-7 happened with less than 5 minutes left in the game. It's over. 2 points is rubbing it in at that point. Which... well, I'm not exactly going to complain if Michigan does that, but it has no game theory application, so if Harbaugh isn't thinking "rub it in," may as well just kick.

Ascending - in a slightly different situation - which took place a couple of weeks ago in Seattle.

MSU scored a TD - then, making the score 29-14 with about 12 minutes remaining in the 3rd quarter.  So, go for one, or two?   My thought - kick the XP - make it a 14 point game.  Let your D get a stop - score again - etc..  

However, this is an example - similar in a way to the Scott Frost decision for an onside kick against Northwestern - where Coach Tucker (like Scott Frost) - has far greater insight and football acumen than I do.

Tucker . MSU went for two - failed to convert - and, watched Washington score the next ten points in the game - to open up a 25 point lead.

Take the point - or points - when you can.   Especially, when you have a decent / solid lead.

Considering that MSU scored four touchdowns in that game and attempted zero extra points, I'm guessing either:

(a) their kicker was hurt
(b) they thought they'd identified a schematic weakness in Washington's goal-line defense they could exploit
(c) they were practicing for their Super Bowl, or
(d) Mel Tucker flunked math.

Forget the one you pointed out, where you can work out a reason to do it if you squint -- they also went for two when down 39-20.  To try to make the score 39-22.  A 17 point -- three score -- game.

Think you throw the book out with Iowa. I just think you take whatever easy points you can get when you are playing that type of team. That game seemed close for a minute, but it was over as soon as we went up two scores.

The "Book" isn't etched in stone.  Against Iowa, taking the point was correct.  They weren't gonna score three touchdowns.  The last td with eight seconds left chaps my ass as most people view that as a closer game.  20-0 after 3 qtrs is an insurmountable lead for that shitty Iowa offense.

"'In both cases the theory is to protect against the most immediate threat. ie., Iowa scoring 3 td's", I can only assume Harbaugh didn't believe Iowa scoring three touchdowns was an immediate threat.

No, we are the school that didn't call a max protect on the last punt/play vs MSU to lose. We are also the school that didn't block down vs App State that got the kick blocked to lose. 

OSU didn't call a fake, Rutgers didn't cover the rugby punt. Hopefully Coach Jay watched that game.

Comments here are dumb. The card exists for a reason. Michigan didn't do the right thing to win. The fact that they still won is moot. 

Hopefully Jay doesn't read this blog or hold himself to these low standards. The coaches made a mistake. Admit it. Don't do it again. Move on.

This is on the head coach, but Jay needs to talk to Jim. Iowa fortunately has the opposite and larger problem, Kirk needs to talk to Brian.

I will take Michigan's problems this week, but if this happens again and we lose... how do you explain that to your team?
