Michael Dyer had some big runs in the first half of the University of Louisville football game against Notre Dame on Saturday in Notre Dame Stadium.
And U of L coach Bobby Petrino knew Dyer would keep running hard.
But in the second half the U of L staff opted to make a switch and get sophomore Brandon Radcliff more touches because of what Petrino said was "his speed."
It turned out to be a big-time move for the Cardinals.
After rushing two times for nine yards in the first half, Radcliff was the man of the hour in the second half and recorded his third 100-yard game of the season. Radcliff finished with 17 carries for 136 yards and one touchdowns in the 31-28 victory.
"We wanted to get him in the secondary and get some long runs," Petrino said. "We wanted to utilize his speed; it was a good change-up."
Radcliff had runs of 7, 8, 9, 10 and 11 yards on the first TD drive of the second half and then came back with runs of 6 and 41 before the 15-yard TD burst on the first play from scrimmage in the fourth quarter.
"He runs hard all the time," quarterback Reggie Bonnafon said.
Radcliff said the offense was told at halftime by Petrino that the Cardinals had to "run the ball if we wanted to win the game."
"And that's what we did," he said. "I was just trying to play aggressive and not let one man tackle me, break those tackles and then try and get into the end zone.
"Man, this is a big game. It's a historical stadium and we really wanted this one. It's one of those games you will tell your kids and grandkids about."
Radcliff said the offensive line was "huge" in the play of the second half. The Cardinals ran for 229 yards as a team, making the 17th straight game with Petrino as the coach that U of L has won when amassing 200 or more rushing yards.
"It was loud out there," Radcliff said. "We had to connect with each other. We got things right and we had to go on from there. It was a great game and a great win.
Radcliff now has 581 yards and nine touchdowns on the season for the Cardinals.
