Peter Schrager of Fox Sports first reported the deal, while ESPN's Adam Schefter said deal is for $2.75 million with $1.25 million in incentives. Boldin played all 16 games, notching 67 catches (2nd on team), 584 yards, and eight touchdowns (lead team).
Despite his age, Boldin still brings a lot to the table, both on and off of the field - especially for a young Bills' offense with mostly young and relatively inexperienced wide receivers.
For more from Beane on Boldin, see the attached video above.
"I was very confident that we were a fit and that he thought we were a fit for him", Buffalo general manager Brandon Beane said. "He had a great visit a couple weeks ago, everything went great".
"It doesn't say anything (against depth)", Beane said. "Sean and I preach family". "Listen, I've been a big Anquan fan from afar".
Baltimore had also been a team that was linked to Boldin previously. "In my opinion, he's a Hall of Famer and he'll teach guys how to be a pro".
Instead, Boldin will combine with former teammate and quarterback Tyrod Taylor in Buffalo where he'll likely be used in the same exact way.
