A lot of the talk about the backfield so far during University of Louisville spring football has centered around the emergence of L.J. Scott.
The true freshman has been sensational through the first three weeks of spring ball and had another solid scrimmage on Saturday, including one touchdown run.
But the star of that scrimmage was another running back - senior Dominique Brown.
The 6-foot-2, 215-pound Brown was the top back, ripping off three touchdowns runs including a 65-yard dash down the left sidelines.
"The offensive line doesn't get a lot of credit, but they did a great job," Brown said. "It all starts with those guys up front."
Brown said the long run was aided by blocks from James Quick and Matt Milton down field.
"I just had to spring down the sidelines," Brown said. "Coach said we were just going to run the ball and (one drive) we just ran it like eight times, I just went down hill."
Petrino said on the long run that Brown broke off he was "faster than I expected."
"I thought he ran the ball, not only the long run for the touchdown, but he made a great run on third-and-two when he got us four yards," Petrino said. "he ran the ball hard and I was really happy with what he showed us."
Brown, who missed all of the 2012 season with a knee injury, was the leading rusher on the team last season with a career-high 825 yards and eight touchdowns. He averaged 5.1 yards per carry and finished fourth in the AAC in rushing yards per game at 63.5 yards a game.
Scott, who is a freshman from Harding, Ohio, added a touchdown and Michael Dyer also scored one TD in the scrimmage.
"As much as the passing game and making big plays there, it's really nice getting big chunks out of the running game," Petrino said. "I was really happy with the running game."
Dyer, the former NCAA title game MVP at Auburn, missed much of last season and had surgery for a sports hernia. He had still been slowed by the recovery but Petrino said he made huge strides this week in practice.
"He showed that he is getting better," Petrino said. "I think in the last week, I have seen his quickness coming back and his vision getting better. He's still a little rusty but he's getting back to where he needs to be."
