'Boldin, 36, had 67 catches for 584 yards and eight touchdowns last season for Detroit. He ranks 14th in NFL history with 13,779 receiving yards and won the 2015 Walter Payton Man of the Year award for his work off the field. A 14-year veteran, he's a three-time Pro Bowler. If signed by the Bills, he would figure to compete with Andre Holmes and Philly Brown for the No. 3 receiver job behind Sammy Watkins and rookie Zay Jones.'
