His total rushing output of 768 yards is third. Western Kentucky's Antonio Andrews has 882 yards. David Fuellen of Toledo has 846. Both have played in six games. Williams has played in five.
Grady Jarrett welcomes the challenge of defending against the 6-foot, 227-pound senior.
"I think they have a very physical run game," Jarrett said. "It's a great opportunity for us to see where we are against a very good offensive line and a very good running back."
But, that rushing attack starts and ends with Williams, who's scored seven of the Eagles' eight rushing touchdowns this season. Myles Willis, the team's second leading rusher, has 85 yards. Tyler Rouse has 58 yards and the other score.
Whoever is toting the ball out of the backfield for Steve Addazio is doing so behind a solid line. The average starter along Boston College offensive front averages 6-foot-4, 302 pounds.
"Very big, like every year since I was getting recruited here and seeing them," Jarrett said. "They're big, physical. We're going to have to match their physicality, get good gap fits. I think it will be a very physical game, will be won in the trenches."
They're experienced, too.
Left tackle Matt Pachan started eight games at Florida before transferring to Boston College. He and right guard Harris Williams are the only first-year starters along the front.
Left guard Bobby Vardaro started every game last year and played 884 snaps. Right tackle Ian White, a nine game starter in 2012, played 657 snaps a season ago.
"They have a really good looking offensive line. It will be a great challenge for us, but we're really proud of our defensive line. We feel like we're ready for it," Jarrett said.
Williams has enjoyed some success against Clemson. Last season, he had 71 yards, including a 30-yard scoring run. As a freshman, he rushed for 24 yards on five carries.
