This story has kind of been floating around out there in the ether. In 2008, legendary tight end Tony Gonzalez asked the Kansas City Chiefs to trade him. The request came during the season, as the Chiefs were full-on rebuilding, and Gonzalez wanted to play for a winner.
Surprisingly, the Green Bay Packers were fully in on Gonzalez (along with the Philadelphia Eagles). The deal never got done, of course.
The Packers had agreed to give up a third-round pick and a tight end for Gonzalez. Gonzalez doesn’t recall who that tight end was, but it was most likely Donald Lee.
