‘I have to go with Sean McDermott. After falling one win short of making a Super Bowl appearance in January, the Buffalo Bills went to work and improved their roster this offseason. Josh Allen had to be happy with the additions to the O-line, backfield and receiving corps, which included veteran receiver Emmanuel Sanders,while the defense retained linebacker Matt Milano and corner Levi Wallace and bolstered its pass rush in the draft. It’s a competitive AFC field, but Allen only seems to be getting better with a team that rallies around him.’
