It should be the patriots, after recent history. Rememeber when they stole our audibles and wrecked havock with Danny's team, and their cb's would maul our receivors...
You can thank our good friend Keith Byars for that (he basically gave New England our entire offensive playbook after Jimmy Johnson cut him). I know this happens frequently in the NFL (Cleo Lemon helped us out last season by giving us the audibles the Chargers use). I know why the players do it. They either do it for revenge (as Byars did) or to help make a team (as Lemon did). I might do the same thing if it it meant the difference in me making a football team. But I wouldn't expect the fans of my old team to forgive me.
