Gruden screwed over several talented White receivers at Tampa, Danny Farmer among them. He also demoted the great Mike Alstott. In Gruden's first year, 2002, Alstott gained 548 yards rushing, but then his production dropped off a cliff -- starting in '03, 77 yards, 230 yards, 80 yards, and 171 yards in '06 his last year. Some of that dropoff was due to injuries, but a lot of it wasn't. I can't remember a Gruden-coached team at either Oakland or Tampa I would call relatively White friendly.
I never liked Gruden at all as a head coach, but I do respect his work as an analyst for Monday Night Football. He's been fair in his often over the top flattery for players, I'm hoping that will be reflected in his next go-round as a head coach after a long time away, but I'm not going to be overly optimistic. Also, his brother in Washington is pretty bad, though working for Dan Snyder there's probably nothing he can do about the basic make-up of his team.
