Anytime a player of Brett Favre's stature appears to have a chance of finding another team, fans will debate the merits of bringing that player to their favorite team.
I don't think you'd find a single person who honestly believes there's a snowball's chance in Hell of Favre coming to KC.
Also, there's very little chance that the Browns will deal Quinn.
It's far more likely they would deal Anderson when they feel Quinn is ready to take over the reigns.
They just resigned Anderson to a 3 year $24 million contract. He's not going anywhere anytime soon! He will keep this Browns team in contention for the playoff for some time to come. Quinn however will not sit on the bench for 4 years or maybe longer depending on how Anderson plays.
