Here's the take on the Cutler trade..
And their final overall conclusion on trading future first round picks...7) Chicago trades its 2009 and 2010 first round picks to Denver for Jay Cutler (April 2009)
Trade made by: Jerry Angelo
Picks lost for: Jerry Angelo
Angelo was entering his 9th season as GM in Chicago when he traded for Cutler. He had overseen an NFC Championship squad under Rex Grossman, and decided to go “all-in” by mortgaging the future to fix the quarterback position. In 2008, Chicago went only 9-7 with a defense that ranked 9th in ANY/A allowed and 3rd in YPC allowed. No principal agent problem here, and the trade nearly worked out for Angelo when the Bears reached the NFC title game in 2010. But that was the high point of the Angelo-Cutler era, and the general manager was fired after the 2010 season.
Conclusion
One thing is clear: in general, trading future first round picks is a poor decision. But most of the time, the impetus for the trade is less a principal-agent problem and more one of overconfidence. General managers see players slipping and believe that they know more than the rest of the NFL. General managers see a “proven veteran” and think that’s worth more than an unproven rookie. Teams want a franchise quarterback, so they see one in the back half of the first round. Teams see a shrinking championship window, and desire to mortgage the future.
On average, these picks don’t tend to work out. In fact, only one of the 18 teams on this list have won a Super Bowl since that trade (although to be fair, only one of the counter-teams that traded for a future first won a title, too). If a general manager wants to trade a future first round pick for a player, he must ask himself why that player is still available this late in the draft. Chances are, the GM isn’t as smart as he thinks he is.
