'The backup quarterback situation for the Bills is unsettled, to put it kindly. T.J. Yates will head to camp as the No. 2, but his performance this spring didn’t inspire much confidence that the Bills will be in good hands if their starter gets hurt. Behind Yates, neither rookie Nathan Peterman nor second-year veteran Cardale Jones looked particularly good, either. Jones heads to camp as the clear No. 4 on the depth chart, which doesn’t bode well for his chance at sticking on the 53-man roster.'
