I'd take Saban in a second.
I live in Miami, he and his wife both hated it here. Big city life isn't for them. So Buffalo wouldn't be out of the question.
As a recruitment tool we would have to offer him full control of football operations. Another way of enticing Nick to come here would be to feed his ego. Tell him that winning here would be better than winning anywhere else. It's the ultimate challenge. Who knows? He might be up for it.
Lastly, we have great talent here in Buffalo. We're not that far off. Glenn, Levitre, Wood, Urbik, Spiller, Jackson, Stevie J, Chandler, Mario, Dareus, K. Williams, Byrd and Gilmore are a nice nucleus to a potentially great team. We're a QB, a WR, a linebacker or two, and a great coaching staff away from competing for a Super Bowl.
It could be done. $10 million a year wouldn't hurt, either. Money talks.
If not Saban, I'd like to see:
1. Greg Roman
2. Bruce Arians
3. Ken Whisenhunt
