'McDermott didn't specifically mention Dareus when talking about being worried about the team's break, but it's natural that his name immediately comes to mind. The Bills need their franchise defensive tackle to actually play like one in 2017. That starts with Dareus actually being available. He's one failed drug test away from a 10-game suspension after sitting out the first four games of 2016 for violating the NFL's substance-abuse policy. For a new coaching staff that has preached how important character is, it would look downright terrible if Dareus were to find his way into off-field trouble again.'
