Yet, he never made a peep.
"It says a ton about his character and what that young man is all about," Andersen said. "I know that guys with his talent want to play, and he has deserved to play and be on the field since day one. He's been extremely unselfish, and kids like that are the foundation of what we've built the program on."
Williams will finish his Utah State career Saturday. And in this, his first and only season as a starter, the 5-foot-8 chunk of muscle has turned into one of the finest all-around offensive talents in the conference, as well as an NFL prospect. Against Toledo, he will likely break the conference career record for all-purpose yardage.
On 200 rushing attempts this season, Williams has 1,277 yards and 12 touchdowns. Always a great receiver, he has 43 catches for 663 yards and another five scores. He combines with quarterback Chuckie Keeton to account for over half of USU's offense. After the season, Williams will play in the East-West Shrine Game, one of the premier all-star showcases for NFL prospects.
"I always knew that I could play when given the chance," Williams said. "But I had to wait my turn. I mean, Robert Turbin and Michael Smith turned out to be NFL running backs, and they are both great players. I just kind of bided my time and took advantage when I had a chance."
Williams has always been serious about football. He was never much of a party guy, and never much for clowning around. From his perspective, he could never afford to. Utah State was his only scholarship offer coming out of high school.
"Football has always been about business," Williams said. "I can have fun in other parts of my life."
With the year he's had, it's a bit easy to forget that Williams made his mark first as a kickoff returner. When Turbin and Smith went down for the season in 2010, Williams started five games and led the WAC in all-purpose yards.
It wasn't easy, and there was a bit of frustration, but Williams returned to role-player status in 2011 with Turbin and Smith healthy. The pay-off, though, has been this season. Williams has been the feature back, and it appears that he may have a chance to perform at the next level.
"I firmly believe Kerwynn will be an NFL draft pick," Andersen said. "He's done everything he needs to. He's gotten stronger, he's gotten faster and he's one of the most mature kids that I've been around. He deserves everything that will come his way."
