So you're going to nitpick one thing in my post, one OC out of a dozen?
Nix came in with a decent prior reputation, he had a better chance than most of those other guys to recruit a good QB (and the theme of the thread is QB recruiting). Nix landed Robert Marve right after he was hired, and he landed THREE quarterbacks (including Jacory Harris) in his second year. That is two consecutive Mr. Football (Florida) winners. The only other Mr. Football winners who have signed with UM were Jammi German and Duke Johnson.
And, yes, Nix's OC stats coulda/woulda/shoulda been a lot better. We went 5-7 in 2007, and outside of the 4 losses to ranked teams, we lost 3 winnable games (at UNC by 6, GaTech by 3, and NC State by 3 in OT). 2007 was a year that we went back and forth between Kyle Wright and Kirby Freeman (though Kirby got us the win at F$U). We went 7-6 in 2008, but we should have won home games against UNC (lost by 4) and F$U (lost by 2).
I agree, Nix's on-field stats were not very good, but his recruiting of QBs was top-notch, so we have to balance out those traits and just give him an "OK" assessment.
