I'm sick of everybody saying that he's done such a good job keeping the team together, that the players are playing for him, that he should get all this credit for relaxing the practices and making it more fun. My take on it is that he basically threw his hands up, and pretty much let the team coach itself, and that's when the turnaround happened (coincidentally, also playing against some weak teams).
According to reports and Burnett's quotes, he basically said - Fine, you want to go 0-16 and get rid of me , fine, but I won't be the only one to go(Wah!). Burnett literally said - He gave us the team! It took Brandon Marshall (the locker room cancer everyone was worried about) calling out Vontae, it took Bush saying -We stink, it took the players saying- We hold each other accountable, and it took Henne literally being physically unable to play for the better QB to get in the line-up.
In other words, injury and the players are doing a better job of coaching this team than Sparano did! Imagine how good we could be if we actually had a professional head coach, not one of Parcell's cronies being handed a job.
