Good thread--a lot good info.
I really don't understand how you can say after winning a Super Bowl, that Parcells hasn't done anything. Being a Head Coach, winning a SB is truly out of your hands. It is in the hands of the player. You have to look at team improvement, realistically. Saying that a team was trending upwards when he entered, is a testament to Parcell's ability to get both players and coaches to create winners. All the players that Dallas depends on now are Parcells' players. Ware, as gifted as he is, could have easily busted under another coach. Tony Romo would probably be a nobody if Parcell's didn't get him. As for Pat White, it isn't Parcells fault that it didn't work out. It falls on the coaching staff and/or Pat White himself. Remember also that Parcells only took two seasons to turn anybody around. He made it look easy to win.
As for the guy talking about how the Lions needs Parcells because Schwartz isn't getting it done. Guy, your team didn't win a game two years ago and drafted three busted WRs in the early first round. It takes a long time to recover from one bust let alone three. You can't create talent out of nothing. It takes intelligent drafting and signing to do that. Schwartz also can't give Stafford a new shoulder. If Stafford stayed healthy his whole career the Lions would be winning more but we don't operate in a world of ifs.
Parcells actual rank out of all is debatable. How he ranks relative to the majority of other coaches. He is one of the best. As I understand it, he is basically keeping his position but losing his title. All he has to do is answer his phone when somebody wants advice.
