I can't tell if you are trolling, honestly believe this, or someone should be calling you an ambulance...
1. The first "real quality staff" Diaz needs to surround himself with is a DC. His current DC is basura. But regardless, all of the coaches currently on the team are Diaz's picks. Other than TRob on staff, what evidence is there that Diaz is even capable of bringing in "quality staff"?
2. Contract law is not your strong suit.
3. If you want to trash Coach Richt for not bringing in quality talent at OL and WR, I don't have much of a rebuttal. But every player on the defense was brought here by Manny. On that side of the ball, Manny's in year 6.
Diaz just isn't it. He needs to go. But that's not all! Blake needs to go. It would probably help immensely if Frenk left, too. And if there was a way to cut the BoT in half (besides a very large, industrial saw) I'd be in favor of that as well (also, let's maybe keep workshopping the saw idea).
