On Monday MGoBlog took a look at current commits unlikely to move up.

Rivals and Scout rankings are useful but imperfect, and early rankings are more imperfect still. Though Michigan freshman Taylor Lewan ended up a 4-star prospect to both major recruiting site, he entered his senior season virtually unknown. By the time final rankings had come out he was a four star well within everyone's top 150. 

The following players look to be this year's Lewan and have some upward mobility this fall. Not all will move up, of course, but look for one or two of the below players to gain a fourth star, or, in Devin Gardner's case, a fifth.

MI QB Devin Gardner

Why Here? Devin has been compared to Terrelle Pryor and Vince Young, so it stands to reason that he is highly-ranked. He took his team to the state championship game (in which the Vikings lost to East Grand Rapids), and put together a solid junior campaign both on the ground and through the air.

All of the recruiting sites like Devin, but none of them love him yet. Barry Brunetti is listed ahead of him among dual-threats on Rivals, and Gardner is still chasing that elusive 5th star on Scout.

Prediction: This isn't much of a prediction. Multiple Rivals analysts have stated flat-out that Gardner will be their #1 dual threat QB and comfortably in the top 100 when they take the Elite 11 into consideration. He has shown off his athleticism—and willingness to compete—by attending various camps and combines in the summer before his senior season despite his early commitment to Michigan. He has shown potential greatness at QB, WR, and even defensive back(!); his versatility is not in question. He killed it at the Elite 11.

Unless he completely tanks this season, anything other than 5 stars will be a disappointment for Devin.

SC QB Cornelius Jones

Why Here? Cornelius Jones's junior season didn't go well. He got exposure during it, playing highly-ranked teams within the state of South Carolina in every game, but his team wasn't good. The competition (like Byrnes, the home of Marcus Lattimore, Brandon Willis, et al, who Spartanburg played twice) was. Jones ended up throwing just 1 touchdown to 12 interceptions.

Michigan extended an informal offer last April and followed through with an official offer in January. He was among the first QBs that the Michigan coaching staff extended an offer to, so they think highly of him despite the inexperience. There's something there.

Prediction: Jones' polish-to-talent ratio is very low, and his learning curve may be quick. A player doesn't have offers in the summer before his junior season if he's not talented (especially when he didn't even play as a sophomore). He's done much better in summer 7-on-7 camps, leading Spartanburg to a tournament final against Byrnes amongst a crowded field of quality programs.

Even if he can't prove his worth as a QB, the recruiting services might rank him as an athlete. If he can have a decent enough year in his senior season, he could end up a fringe 4-star guy. At the very least he should pick up a third star from Scout and get bumped up a bit in the positional rankings.

One heartening item: his high school coaching staff will have a year under their belt coaching as well. Last year was their first in Spartanburg.

TX RB/Slot Tony Drake

Why Here? Drake is the sort of guy who can excel in the Rich Rodriguez offense, but isn't likely to be considered for a high ranking by the recruiting sites. He's a speedy little bastard who performs despite his diminutive stature, and probably wouldn't last long in the NFL.

Drake was productive as a receiver as a sophomore, but was relegated to a backup running back last year.

Prediction: He is at one of the right programs to have success at: Skyline routinely pumps out a talent, and is one of the most visible high school teams in the nation. The stage is set for Tony Drake to take a big leap forward.

Now he just has to perform. Being named second team all-district at WR as a sophomore proves he might have the skill to get it done. I was pretty dubious on Drake's ability to move up, but there is an the opportunity in front of him.

OH WR Jerald Robinson

Why Here? Robinson hasn't gotten it done on the field yet. A bad QB situation may have played a role in that. He is also a multi-position player that nobody knows exactly where to place. Originally, most Michigan fans thought he would play safety. After an impressive camp performance, however, nobody knows quite where he will play. At the moment, it seems like he'll stay at wideout.

If the quarterback situation at Canton South doesn't get better, Robinson won't have a opportunity to produce. However, if it improves, he can move up with a much better year.

Prediction Sam Webb was really high on Robinson as the best wideout at Michigan's camp, which was also attended by the likes of Ricardo Miller and Jeremy Jackson. That alone indicates that Robinson is an talent deserving of 4-star status.

With impressive performances this summer—and hopefully a better season as a senior—Robinson will have a shot at getting a fourth star on Scout, too.

OH WR DJ Williamson

Why Here? DJ Williamson is unknown. Though he has a highlight film on Scouting Ohio, the recruiting services either don't know much about him or didn't deem him worthy of even a 3-star ranking until recently. Williamson committed early and has not attended any camps, so his exposure is very low. Scout and Rivals both have him at three stars (finally), but he is way, way down on each of their wideout lists.

There is upside here: Williamson has decent size at 6-1 showed elite speed by winning the 100m dash in meet after meet on his way to the Ohio state title.

Prediction: If Warren finds a quarterback to get the ball to him, Williamson's size and speed alone should boost him up to a high 3-star. Four stars is doubtful for a guy who hasn't put in the time at combines and camps.

MI WR/TE Jeremy Jackson

Why Here? The son of a coach, Jackson got early offers from the likes of Florida and Texas before ending his recruitment early. He is a polished player as a coach's son. He had good, but not exceptional stats as a junior.

Players who have received lots of coaching in their careers but aren't dominant in high school, usually don't have the physical talents to be elite players. And with Huron moving to a veer option offense, Jackson may not have a lot of opportunity to prove that he deserves to be ranked among the top players in the nation.

Prediction You may be taken aback at first by the fact that Jackson is listed as a WR/TE. Sam Webb has been saying on the WTKA recruiting roundup for quite some time now that Jeremy is still growing, and currently looks more like a tight end than a wide receiver. With Michigan's new focus on athletic tight ends, they might encourage a further move in that direction. Jackson may have more upside there, and if the recruiting sites make this change in position, he could move up to a 4-star prospect.

[Editor's note: I would have slotted Jackson in the other group; he's polished and slow-ish, two things that don't often result in big senior-year moves. Also: high school to run a veer. To be fair, Tim's basing his assessment on Jackson as a tight end.]

OH DE/LB Antonio Kinard

Why Here? Kinard is the third in the trifecta of tweeners Michigan has committed on defense (the other two, Ken Wilkins and Jordan Paskorz, were listed as “Stuck in Neutral”). He doesn't stand out on film more than most prospects, which leads to his 3-star ranking. And with two classmates a year older heading to Michigan, he probably got at his fair share of scouting.

But Kinard is athletic, as evidenced by his huge TD run in the game that I scouted with VB last year, and Duane Long also thinks he's got serious athletic ability.

Prediction: Kinard wasn't highly productive on a defense last year that featured current Michigan freshman Isaiah Bell roaming the secondary. You'd think that an imposing safety like Bell would give Kinard more opportunities to make plays, but he didn't. He has the athleticism, though, the potential for big time production is there.

Unlike Paskorz and Wilkins, I think Kinard is likely to stay at LB. Still, I think he'll be a low-4 or higher 3-star prospect. A big move is unlikely for a tweener.

OH CB Courtney Avery

Why Here? Avery, a star for Lexington High School for the last three years, is not underexposed. The problem is that he has starred as a diminutive quarterback. Avery only started playing on defense just this past year, but couldn't go full time since he was busy tearing up opposing defenses on the other side of the ball. Now that he knows where he’ll play in college, that might change.

If Avery was a couple inches taller. He could be a Troy Smith clone (not that Smith was a giant) and use his pinpoint accuracy and athleticism to direct Michigan's spread offense. Alas, he's not, so unless he's used for the occasional trick play on offense, he'll be a corner for GERG's defense.

Prediction  Avery has some of the best upside in Michigan's entire recruiting class so far. Local observer Duane Long thinks Michigan got "a steal." Avery is just one year into his new position, potentially still growing, and was deemed good enough by Michigan's coaches to receive an offer at camp after a week of personal observation. If he can take enough time off from blazing through opposing defenses, he should be able to move up in the rankings. Avery's a quintessential late mover.
