Demanded A Trade: Jay Cutler
Metaphorically speaking, when a new chef takes over, he almost always wants to bring along his own recipes. Of course, in this case, neither the new chef or the old recipes were worth it in the long run, anyway.
When the Denver Broncos hired away Josh McDaniels of the New England Patriots to be their head coach, there was an immediate rift between McDaniels and incumbent quarterback Jay Cutler, who was a top pick of the previous regime (led by Mike Shanahan), when McDaniels lied and said the team wasn’t entertaining trade offers for the quarterback when they clearly were.
Cutler demanded a trade, eventually ending up with the Chicago Bears.
