Donovan McNabb vs. Terrell Owens
T.O. has apparently never heard the saying "don't bite the hand that feeds you," because after McNabb campaigned for the Eagles to sign Owens in 2004, connected with him for over 1,200 yards and 12 TDs, and took him to the first Super Bowl appearance of his career, the controversial receiver criticized McNabb's performance in the championship game. Owens also complained frequently about not getting the ball enough, and even said that the Eagles would be better off with Brett Favre. McNabb took offense to the final comment, calling it "black on black crime." The two were caught arguing on the sidelines several times before Owens' comments earned him a one-way ticket out of Philadelphia.
