Donut is the definition of a FOOL! Given whatever reason for the failure of his scheme, coaching, talent or comprehension, you can't keep doing the same things and expect different results. It's like having a NASCAR with a little old lady driver. Donut does not have the aptitude to adapt a defense to fit the talent. He's a basic computer coach. He can only do what he's been programmed to do.
Is the entire team ready to go? Are the coaches ready to go? Football is the ultimate team sport. One guy doesn't mean more than a bunch of jelly beans...
Prolly have 5 sacks in his first game back, get benched for " freelancing" and find himself back in Al's doghouse for unspecified " violation of team rules."
