Moss always believed he could still perform

York told reporters earlier Monday at team headquarters his team needed "someone to stretch the field." The athletic, 6-foot-4 Moss fits the bill.

Moss said he initially retired for "personal reasons outside of football" and considered making a comeback late in the 2011 season before ultimately deciding to give his body more time to train. He suffered a shoulder injury during 2010 with New England.

Moss always believed he could still perform.

"It was a decision to get back in the game because I still love the game and think I can play at a high level," he said. "It was obvious they liked what they saw. I don't want to let them down."
