This trade is the root of the J.J. Arrington (2010) trade tree — the full chain is traced there.
Philadelphia swapped linebacker Joe Mays to Denver for running back J.J. Arrington, with a safety net: if Arrington didn't make the team, the Eagles would get a 2012 sixth-round pick instead. He didn't, and Philadelphia used that pick on receiver Marvin McNutt.
On July 30, 2010, Denver Broncos sent a 2012 sixth-round pick (No. 194, became Marvin McNutt) to Philadelphia Eagles for ILB Joe Mays.
