You implied it by mentioning him and Parcells when you said no coach can be successful under Jerry. Your defense of Garrett should never include coaches who have won championships and in this particular case, multiple championships.
And it's funny how you put down Wade and the talent on the team, when Wade's first 3 seasons and Garrett's first 3 seasons, with practically the same players, are so disparate. Wade, if allowed to finish his 4th season, would have only ONE losing season in his tenure as Cowboys coach. This is the same team that set franchise records for most players sent to Probowl. Wade won NFE twice with that overrated talent in his 3.5 seasons.
And one of the reasons Cowboys offense started to falter was the loss of Owens, which was the direct result of Garrett before he became HC. I would take Wade as a coach, at any level, over Garrett any day. A Lombardi and 2 conference championships speaks for itself, never mind how dominant HIS defenses have been his entire career. Wade can take hiz'n and beat ur'n and vice versa, Garrett never has been able use his own talent to its fullest until Linehan came on board.
