Buffalo Bills’ training camp practice will be underway in a matter of days, and four hot position battles will unfold. Following June minicamp, Bills On SI identified four positions that appear entirely up for grabs heading into summer. First, and foremost, the Bills will look to settle on starters for their second cornerback and safety roles. In addition to the two starting spots in the defensive secondary, Buffalo will have a new third tight end and a different fifth wide receiver this season.
