They only parted with a 2010 second round pick. The deal immediately completes the Falcons offense, while solidifying up that Pettigrew will not be drafted by the Falcons.
The Falcons have just showed that they may have their eyes set a lot higher then the process. This is not to say they are breaking away from it, but the Falcons offense is now championship caliber.
For those of you who say that a tight end cannot put an offense over the top, well I say the best tight end in NFL history makes every team better.
