‘While the Buffalo Bills could certainly come away from the 2015 NFL Draft with a quarterback, the prevailing opinion is that the 2015 Senior Bowl lacks a difference maker at the position. In past years, players like Philip Rivers, Russell Wilson and Derek Carr have been able to steal the show in Mobile. On Tuesday, the best quarterback was probably Colorado State’s Garrett Grayson, who has a chance to play himself into the second day of the draft with a strong showing this week. If the Bills are looking for a mid-round quarterback with some upside, Grayson fits the bill.’
