PITTSFORD, N.Y. (AP) - Receiver Anquan Boldin says he doesn't have anything to prove and is instead focused on leaving a legacy as he begins his 15th NFL season one day after signing with the Buffalo Bills.

Boldin deemed the Bills to be a good fit and dismissed the notion the team can't be a considered a contender despite being in the midst of a 17-year playoff drought. The 2015 Walter Payton Man of the Year also welcomes the role of being an on- and off-field mentor to Sammy Watkins and Buffalo's young crop of receivers.

Boldin showed no indication even at 36 years old of having lost a step during his first practice Tuesday. He spent the entire offseason waiting to land a job.

During an individual drill, Boldin easily maneuvered through a number of pylons and made a one-handed catch just before running out of bounds.
