The undrafted 33-year-old pass-catcher began his productive career in Miami in 2004 after a one-game pit stop with the Chargers. In his third season in South Beach, he caught 67 passes for 687 yards and one touchdown. Welker was then snatched up by Bill Belichick, who traded second- and seventh-round draft picks for the rights to the receiver.
A rash of concussions has put his career in jeopardy after 11 seasons. Welker started just eight games and missed two contests last season after a PED suspension. His lack of separation on cornerbacks led to just 49 receptions and 464 yards receiving -- his lowest totals since he got receiver minutes in his second year in Miami.
