'Alexander, 33, had a breakout season in Buffalo last year with 12.5 sacks. The Bills re-signed the former edge rusher despite questions surrounding his fit in the new defensive system under McDermott. Alexander thrived in a 3-4 under former head coach Rex Ryan, but McDermott will run a base 4-3. Along with his sack total, Alexander had 76 tackles and an interception, all career highs.'
