According to ESPN:
Now the chiefs managed to get Cassel for a second round pick, so I find it a little surprising this deal wasn't completed. With Cutler now very unhappy, I think a strong move for Cutler now could possibly pry him away from the Broncos. Cutler is mobile, has a strong arm and is coming off a pro bowl season. He'd give the Bears offense an instant level of credibility it hasn't seen in years.
The source said Tampa Bay, Detroit and Chicago could be possible destinations if Cutler gets his way and is traded.
Personally I would love to see Cutler in a Bears uniform. While I don't know that Cutler truly is a long term elite quarterback, I would like to see JA and company roll the dice and bring in a guy who would be the youngest and most talented QB this franchise has seen in years. Second and Third round picks and Kyle Orton? I'd make that trade.
