I debated putting this in the Rivals 100 thread, but this is good info and didn't want it buried. Here is the link: http://footballrecruiting.rivals.com/content.asp?CID=1328720
Some of the pertinent information to Michigan is below, the live chat is not paywalled and is still going on right now:
At No. 18, obviously Ty Isaac certainly has a shot at earning five-star status. Both ND and Michigan are very high on his list, if not the outright top two teams on his list, but no, I do not believe he is close to being decided on where he wants to go.
Guest - I feel Jake Butt has the highest upside at TE, but he can definitely play DE at the college level and is being recruited as such. Strictly as a defensive end he's really a four-star caliber prospect too
Tim- Tunsil doesn't claim an outright leader. Florida, Georgia, Alabama, Florida State are some of the main schools in the picture right now.
Folks, remember the Rivals250 will be released tomorrow and we will have a chat following that release as well. Save your questions on those who are not in the 100 because they may be in the 250 tomorrow
Michael, we have seen Tuley-Tillman on film and in person. Great prospect and definitely considered for the initial 100. I suspect you'll see his name tomorrow
Obviously whether or not a player earns another star is based on what goes on this off-season and into their senior seasons. At No. 16 Shane is right on the cusp of five-star status so he definitely has a shot to earn that in the coming months
Guest: Shaq (Wiggins) is still developing ... Great young talent. Physically not where he needs to be yet. He knows that. That's the best part about Shaq. He's a mature kid who plans to address his weaknesses.
(on who could see a significant rise in the rankings this year) Guest - in the Midwest it could be a Dymonte Thomas or Evan Lisle. With Lisle, we just want to see how he adds weight. Right now he looks like a college tight end, which is a good thing, not a bad thing. With Dymonte we want to see him more in coverage, make sure that aspect of his game is on par with his position
