Let's be clear.
What Philly is doing may not work. We may all look back a year from now and Barkley was hurt and barely played, Huff turned back into a pumpkin, etc.
But I think at this point, what makes some Cowboys fans jealous is that the Eagles are willing to change it up, change up their strategy, cut bait early on guys that are mistakes, etc. They acknowledge their shortcomings, they come up with a plan to address it and rightfully or wrongfully are aggressive in executing that plan.
What we have is a GM who is afraid to admit mistakes, whose ego prevents him from admitting mistakes, who is too arrogant to admit mistakes and basically repeats the same thing each and every offseason because he's tricked himself into believing he's smart than everyone else.
