Goodell can rescind the deal if he feels that it damages the integrity of the league by being too one-sided. He can tell the parties to go back and adjust the deal. All it takes is a call to the Broncos and to the Bucs to find out if there was any substance to the rumor of the 3 way. If there was, and it involved the #12 pick, then Goodell has grounds to rescind the deal because the #12 pick would be worth two 2nd rounders.
Now, I am NOT saying that this is true. I am just saying what can happen.
That would be deal that Tampa reportedly offerred AFTER the Pats/Chiefs filed the paperwork on their trade and that Denver has publicly said they wouldn't make?
