I bet Jerry wishes he managed to keep Sean Payton around for one more year.
Or just have kept Parcells for 1 more year, when Cowher would be available, and perhaps even Lovey Smith. Smith has just 1 more year left on his contract, and though you would think that Chicago would give him a big fat new one, he conceivably could have also refused to sign a new one with Chicago in order to go to a dream job less than 2 hours from his Texas hometown.
