Pretty much all season long, and especially since Wade Phillips has been fired the talk around DFW is not if, or when, but which Super Bowl winning coach should the Cowboys hire to replace him. Sure Jason Garrett won his first game, but nothign would make the populace happier than getting John Gruden or Bill Cowher. Maybe even Brian Billick. It is something I've been thinking about as well. The question is, is it worth it?
The short is answer in the history of the NFL (Super Bowl era at least) is no.
We can delve into the longer answer. Basically only Bill Parcells and Mike Holmgren really got close. Winning one with one team, and they both took another team to championship. Two others lost the big game, and then went on to win (Dick Vermeil, and Don Shula). Vince Lombardi won at Green Bay and never did much with the Redskins. Hank Stram won at Kansas City and then only posted 7 wins as the head coach at New Orleans. So basically just don't go too crazy about signing that big name coach with a Super Bowl win under his belt. It hasn't worked yet, but then again maybe they are due.
