NFC East
Joe Gibbs and Bill Parcells have five Super Bowl wins between them. Tom Coughlin took an expansion franchise in Jacksonville and had it in the AFC championship game in its second year.
The NFC East, however, belongs to Andy Reid.
Reid took over the Eagles in 1999, went 5-11 with Donovan McNabb as a rookie and is 46-18 since, not counting the playoffs. The only stain on his record is three straight losses in NFC title games.
