Purely talking "should", Brady "should" be traded this offseason to a team willing to fork over multiple first round draft picks. It's the Patriots way. Move on a year too early, particularly if you can get something big in return. See Mankins, Logan. Seymour, Richard.
Despite the fact that the Pats "should" do this, they can't. Brady is too iconic. The fans would go ballistic. It's better to have him play out the final three years of his contract and ride off into the Hall of Fame, having played his entire career as a Pat.
All I said was that, if Brady starts bellyaching about his contract and holding out for more money, he would be giving the Pats permission to honor his wishes and dealing him to a team that might be willing to offer him a bigger deal. I don't expect Brady to complain about his contract, either in public or in private, but if he did, trading him wouldn't be to punish him. It would be because trading him is really the way to max out the club's value in the player.
Would you rather have one more year of Brady or two #1 draft picks from a team near the top of the draft?
