How can the missed assignments by the OL be fixed?

Do offensive lines get better at identifying blocks as the year progresses?  How about with a new OL coach and shared OL coaching duties?

The recent UFR (and posts derived fom that UFR) illustrate that our biggest problem is OL missing assignments.  When they engage, they are talented enough and do fine.  I think it is the single biggest flaw on the whole team that affects the pass and run games more than anything (especially with young receivers and new QB).

I looked back at this year's UFRs.  The picture looks bleak:

Florida UFR:

Michigan appeared to have a severe Kalis issue where guys would run by dudes it seemed like they really really needed to block.

I had a lot of Ulizio minuses because he'd run by a DE and that guy would subsequently run by a TE with basically no shot at making good.

Cincinnatti UFR:

These big mental errors were collectively –10, or approximately half of Michigan's minuses on the day. Will they continue? At some level certainly. They are likely to drop off as these two second year players move along.

Air Force UFR:

Michigan's blocking was a little substandard as they failed to cope with blitzes too often.

Kugler, meanwhile, had a rough day and might have been responsible for more stuff than the obvious. Air Force had a number of plays on which Michigan looked befuddled. Sometimes that's individual players. Sometimes that's the line call. Kugler consistently failed to adapt to the nose tackle exiting stage right, and a couple of plays on which some other sap looked bad were issues with either Kugler's ability to ID a blitz or the presnap line call. He got some –2s when he decided to block a guy who was very obviously leaving for another gap.

And, of course, you just read the Purdue Offensive UFR.  Same issues.

So, does this type of thing typically get better throughout the season?  Is it the Center's fault in failing to make the right line call and should Cole move back? 

How about Greg Frey?  Where is he?

From a 247 article on Frey joinging Drevno:

With the vacancy created by the departure of running backs coach Tyrone Wheatley to the NFL Jacksonville Jaguars, Wolverines head coach Jim Harbaugh decided that having multiple minds of different philosophies working together could make the offensive line unstoppable.

"We’ve had a lot of great discussions on how to block things, on how to handle things," Frey said of his conversations with Drevno. "Picking up twists, stunts and bringing two really good styles of offensive line play and coaching together in that world has been outstanding.”

Are the different backgrounds causing confusion? Did Frey mention this in the interview to telegraph that there was some divide (or power struggle) over how the line calls should be handled?

EDIT - BONUS QUESTION:  Is it possible that the complex blocking schemes and need for someone experienced to ID blitzes is what lead to Speight getting the starting nod? If my OL (or center) can't seem to figure out a line call when the defense moves, then I lean towards the most experienced QB just because of how important it is to pick up the blitz.
