Uche may be great, but I reeeally don't think Michigan's LB cohort (Bush, Hudson, Ross, Singleton, Anthony, Gil) is lacking in terms of athleticism.
At safety, I like the depth with Hawkins and JKP. But I also feel good with Metellus and Kinnel tacking on an extra year with Don Brown. Especially with everything Ambry can do when floating around in nickel packages.
That detail about Nico at WR is fascinating. I've been excited for him and am not fully in-line believing this rumor. But if it is true that he passed DPJ and/or Black, that's incredible. There are two camps on Jim McElwain at Michigan: that (1) he's a doofus HC and what are we doing or (2) holy crap, that's a tremendous WR coach hire and that we really lucked into his HC career tanking. Either way, I doubt he stays more than 1 year, and even if that, I'd even further doubt he lasts beyond 2. But if he gets back to his original chops and takes this chance seriously, this WR roster can really blossom.
And then for Hudson > JBB? Man I hope so. I don't know who would be better v. ND, but I am persuaded that Hudson has significantly more upside and would improve more as the season progresses.
