If you have watched any interviews by Michigan players or coaches over the last week, you may have noticed a lot of them have been talking about the 3-3-5 defense. MGoBlog recent post here gives the impression that Michigan has made the switch to the 3-3-5, and the majority of defensive plays will be in this formation.
Personally I'm a big fan of this defense, and it should be well suited to Michigan with the speed that they have on defense. I'd imagine that Greg Robinson will keep all his hybrid players however, such as Craig Roh as the quick (DE/OLB), Mike Williams (who appears to be trying the new Stevie Brown role this spring) at spinner (S/OLB) and players like Kovacs as a box safety.
Anyway, in terms of recruiting, this must change the focus of defensive recruiting slightly. Recruiting the safety position will be very important over the next year or so to provide decent competition at the three spots. Fortunately Michigan got one of the best safeties in the nation last year - Demar Dorsey, as well as a handful of others such as Marvin Robinson and Carvin Johnson.
If we look at the safeties in the 2011 class, Ha'Sean Clinton-Dix will definitely be a target down the stretch. He is a teammate of Demetrius Hart, and the two players are considering going to the same school, Michigan is one of those under consideration.
Another good safety prospect is Ohio's Ron Tanner. He has been to Michigan twice now, and seems to enjoy it up there, however the Buckeyes have come on strong for him as of late and the word is a commitment could come before his senior year.
