‘Alexander must be able to do at least as much as he did in 2018, when he helped the Bills rank second in the NFL in yards allowed with a career-best 69 tackles. He also had 6.5 sacks in 16 games, including eight starts, and had a career-best two interceptions. In short, Alexander has to contribute the way defensive tackle Kyle Williams did last season, which was his 13th and last. The Bills feel fortunate Alexander fills Williams’ leadership void.’
