‘Josh Allen is set up for success, with the Bills returning nearly every starter from a team that won 10 games and reached the playoffs. Buffalo added a No. 1 wide receiver by trading for Stefon Diggs and improved the running game by pairing Devin Singletary with third-round draft pick Zack Moss. The defense lost veteran linebacker Lorenzo Alexander, an irreplaceable locker room presence, and its top two sack leaders from a year ago in defensive linemen Jordan Phillips and Shaq Lawson. But Buffalo mitigated those losses by signing Mario Addison and Vernon Butler and drafting Iowa defensive end A.J. Epenesa in the second round. Josh Norman, another free agent acquisition, could earn the starting cornerback job opposite Tre’Davious White.’
