‘It wasn’t that long ago that John Miller was named the most improved second year guard by Pro Football Focus. Unfortunately for Miller and the Bills, the guard couldn’t build off his sophomore season. He only appeared in four games in 2017 and lost the right guard job to Vlad Ducasse. One of Miller’s biggest issues last season was an ankle injury. If he enters training camp healthy, Miller has a chance to bounce back and win the left guard job.’
