Couple things from the Crayton talk... Parcells worked them really hard. As one example, first day of camp, the first thing they did was live goalline. I seriously doubt Jerry would even let a coach do that anymore. (Not the goalline but the overall approach.)
Good Garrett stuff at 1:36. Crayton seems like a good dude and doesn't go crazy trashing him, but yeah, he says several times that Garrett was a proven liar and everyone knew it. Also, Crayton had a good point on a blitz adjustment, and an assistant coach said Garrett made the offensive coaches stay up there late at night just so Red could try to convince everyone it was his idea and concept. That's how big his ego was. Also, yeah, he definitely sabotaged Wade.
