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).

With the Cowboys, he coached Tyron Smith, Zach Martin and Travis Frederick to Pro Bowl seasons. In New York, Nick Mangold, D'Brickshaw Ferguson and Alan Faneca earned a combined nine Pro Bowl selections under Callahan's tutelage.

But despite all of the individual success and talent those six players possess, none of them have the ability that Trent Williams has, Callahan said.

"Well I consider him the best, I've been very fortunate to be around a lot of all-pro tackles and this guys off the charts athletically, I mean I tell him that all the time," Callahan told host Larry Michael on "Redskins Nation." "And what he can do with his talent level whether it's on the perimeter, at the point of attack, downfield on screens, it's scary, it really is."

During his first five or so seasons with the Redskins, Williams was always applauded for his ability despite the fact that many considered the team's offensive lines as one of the team's weaker units.

And although he was 6-foot-5 and tipped the scales past 300 pounds, Williams was quick and athletic enough to excel in Mike Shanahan's zone-blocking offensive scheme that tends to employ smaller offensive linemen.

But between wanting to curb a family history with diabetes and wanting to get just a little bit slimmer to improve his overall health, Williams lost more than 20 pounds last year.

"Losing the excess weight, it helps me in every facet of my life," Williams said in November. "I'm able to recover quicker. My joints don't ache as much. I'm in the 12th week of the season and opposed to banging my knee on the ground, I feel great. I feel like I move faster. Obviously my wind is a lot better with taking the weight off, so it's helped me tremendously, man."

While Williams, 27, is just hitting the prime of his career, Callahan believes that once the four-time Pro Bowler decides to hang up his cleats, Canton will soon be calling.

"He's got the type of feet that Hall of Famers have," Callahan said. "And, boy, as he keeps putting together these years, stacking these years, back-to-back Pro Bowls and All-Pros, someone will have a decision somewhere down the line."
