‘Yet the draft involves more than one round, and the Bills’ needs go beyond a tall wide receiver and a tight end who is able to open up the middle of the field for their passing game. They also will return a fullback to their offense and once they trade ex-starting quarterback J.P. Losman, as expected, they still need a reliable backup. He’ll probably come through what’s left of free agency. They could also use an upgrade at backup center.’
