Michigan fans were extremely excited to see the 2012 class finish as one of the best recruiting classes in recent history, and Brady Hoke hasn't wasted any time in securing what is almost surely a top-5 2013 class, if not a top-2 class. The 2012 class is a top-heavy class with five-star talent at the top and extremely raw players at the bottom, and although the 2013 class isn't exactly a stark contrast it has a few more boom/bust players with higher ceilings and ultimately more volatility. In the stock market this means a risk of both a large gain and heavy loss, in football this means running the risk of offering a player who could turn out to be great but could also end up filling a roster spot without contributing.

The 2013 Boom/Bust Prospects
DE Taco Charlton
Charlton is the reason why the boom/bust post was born. He's the epitome of a boom/bust prospect, and I think his ceiling is very high. He has all of the physical tools one would look for in a WDE: height (6'6"), a frame that can hold plenty of muscle, enough length to fight off most offensive tackles and enough speed to scare them into taking a false start penalty. He jumps over freakin' dummies. If he combines all of his athletic tools with coaching he's going to be in the mind of every quarterback he faces.
Floor: Role Player
Despite all of the above attributes he's extremely raw, and the word extremely shouldn't be understated. Physically he needs to get stronger in order to become an effective run stopper. His showing at The Opening was anything but consistent, losing to some and only beating others with his one legitimate move: the speed rush. Despite being one of the 1-v-1 wins leaders he managed to display poor leverage, being thrown to the ground on camera by a tackle who caught him on the outside. He needs a great deal of general technique work, and if he doesn't add more moves to his repertoire he could become a situational speed rusher.
CB Gareon Conley
What makes Conley valuable is his combination of length and quickness. It might sound odd but Conley reminds me of Steve Breaston in his movements, and I'd like to think that Steve Breaston would have made one hell of a cover man given the proper coaching. Gareon's lateral agility and acceleration are both plenty good enough to be an all-conference performer, and although he's not a blistering straight-line runner his speed is above average. Add decent instincts and ball skills and you've got yourself an underrated recruit.
Floor: Bench Player
Like many of his fellow boom/bust teammates Conley is too weak. He's reportedly 6'1" yet only weighs 165-170 pounds. A corner as tall as Conley needs to weigh at least 185 pounds before he can hope to get physical with BCS-level receivers or tackle strong backs, and these boom/bust corners often lose a bit of agility in order to get stronger, making them a lanky safety or a slow corner. Improbable, but feasible.
DT Maurice Hurst
Hurst is slightly smaller version of Ondre Pipkins. At 6'2", 300 he's a bit on the short side but makes up for it with athleticism. Like Pipkins he moves much faster than people his size should, playing both defensive tackle and running back for his high school squad. Yes, he's a 300-pound running back. Scary? Scary.
Floor: Role Player
Just like Pipkins he needs work in terms of technique, making him the prototypical boom/bust defensive tackle. The major difference between he and Pipkins is lower body strength, which is what separates him from being a unanimous top-100 player instead of a borderline 3/4-star player. If his leg strength remains below average he'll be a DT who is only needed because the Wolverines are so damn desperate inside.
CB/S Channing Stribling
Ceiling: BCS Starter
Stribling is a poor man's Leon McQuay. He'll be given the opportunity to play corner in Ann Arbor because he's quicker than many corners standing at 6'2", 170. His strength's include a nasty tackling nature and the ability to high-point balls.
Floor: Transfer Candidate
Once again, Stribling needs to add more mass than most cornerback prospects, and even more so if he ends up at safety. I doubt his ability to stick with BCS-level receivers as a corner already, and he has a long way to go before he's physically ready to play safety. Michigan has recruited both CB and S well enough to create depth, so if Stribling ends up in the previously mentioned no man's land between the two positions he'll look to find somewhere else to play.
OT Logan Tuley-Tillman
LTT has a great amount of potential, and his four-star ranking reflects it. At 6'7" he easily has the height and length to deal with any defensive end, and on top of that he already weighs more than 300 pounds, so we know that he has a suitable frame. He's more athletic than many of his tall, heavy counterparts and has flashed decent footwork in camps.
Floor: Bench Player
Tuley-Tillman's weight isn't all clean and he'll need to convert much of it into muscle. This may seem like a given for an offensive lineman but it's more of a concern for LTT than many of Michigan's other OL recruits. He has struggled at times on the camp scene against speed rushers and it could become a problem at the next level if he doesn't clean up his frame. Aside from that the usual technique concerns apply, and although they're not major Michigan won't be hurting for elite tackle talent for quite some time. This means it's improve or get buried on the depth chart.
