While he's only worked with Trent Williams for one season, Redskins offensive line coach Bill Callahan believes Trent Williams easily has Hall of Fame ability.
A veteran of 17 NFL seasons, with stints working in the college ranks, too, Bill Callahan has seen and worked with some of the best offensive linemen football has had to offer over the last two decades.
Prior to joining the Redskins as the team’s offensive line coach before the start of the 2015 season, Callahan’s two most recent stops were with the Dallas Cowboys (offensive coordinator/offensive line coach) and the New York Jets (assistant head coach/offensive line coach).
