Ron Brown has accumulated his share of sports-related sayings over the years.

He tossed out a good one Wednesday.

"Throw your heart over the bar, and your body will follow -- that's what they tell the good high-jumpers," he said. "If you have to conquer a barrier, you have to throw your heart over it first."

That's what Rex Burkhead did Friday at Iowa, Brown said. The senior tailback threw his heart into the performance, rushing 16 times for 69 yards after sitting out the first half -- and the previous four games -- with a knee injury.

Nebraska needed him in the second half. It says here NU wouldn't have won the game without Rex. Burkhead responded to the call. Responded to adversity.

"It's your response to adversity that makes or breaks you as a man," Brown said.

So what will Brown do with Burkhead on Saturday? Start him?

"You play him," the Husker running backs coach said with a chuckle. "He's in the game plan. I don't care if he starts; I want to know who finishes. He's the best finisher in college football. That's what I love about him."

Brown said "there's a place" for all four of the tailbacks -- Burkhead, Ameer Abdullah, Braylon Heard and Imani Cross.

"We'll see how the flow of the game goes," Brown said. "They're unselfish guys. I told them this week I'm just so proud of them because we needed every single one of them to get to where we're at right now. Every single one of them had an impact on the season, including the fullbacks.

"Who would've thought Rex Burkhead would've been down all the time that he was, and we still lead the conference in rushing?"

Burkhead practiced well this week, and with a lot of confidence, Brown said.

"He looks great."

That's obviously great news for Nebraska.
