It's something free on Rivals to read. From what I've read, Rivals has typically been down on Michigan recruiting so there are a few interesting thoughts from Mike.
"The recent addition of Dallas Crawford certainly helps, but it's a small defensive class so far. However, it's not a bad one at all. Brennen Beyer is a very good player and Delonte Hollowell has a lot of upside and athleticism despite being small for a cornerback. Greg Brown is also solid at defensive back and Kellen Jones has upside as a linebacker. Chris Rock has upside as well but I'm not as sold on him as the others in this class.
Michigan needs to add Anthony Zettel for sure. He could be the most important recruit left on the board, and Kris Frost would be a huge boost to the defensive class. I think the Wolverines lead for both. They also lead now for cornerback Blake Countess.
Michigan is involved with a bunch of other top defensive prospects such as Hasean Clinton-Dix, Doran Grant, Avery Walls, Timmy Jernigan, Deion Barnes, Branden Jackson, Mickey Johnson, Austin Traylor, Darian Cooper, Lamar Dawson and others. While they don't lead outright for any of them, I think they can pull a couple of them. A lot depends on how Michigan finishes the season but it appears that Rich Rodriguez is safe so I expect a good finish in recruiting."
