In case this hasn't already been posted, I got this over at Tandler's Redskins Blog:
"Coles' main complaint about Gibbs was the coach's inflexible nature. "I didn't feel respected as a player," Coles said. "I know everything changed [when Gibbs succeeded Spurrier] but when you feel like you're one of the best players at your position, you'd think you could talk to a coach about the play-calling. We didn't have that situation.
He called the plays. We ran them. That's where things fell off with me. I realize it's a dictatorship but there's only so much you can take."
