Jeff Brohm is a few days away from facing his toughest challenge as the head coach at Purdue.

On Saturday, the Boilermakers will welcome No. 2 Ohio State in a prime time matchup (7:30 p.m., ABC) to Ross-Ade Stadium. Both teams own two of the most explosive offenses in the B1G, setting the stage for a shootout in West Lafayette.

It will also mark the first time in Brohm’s short stint that the Boilers will face a team ranked in the top five.

At his weekly press conference on Monday, Brohm spoke highly of Ohio State, referring to the Buckeyes as one of the two “elite” programs in college football. Alabama was obviously the other.

“When you look at the college landscape there’s two teams that stand out as being elite, and that’s Alabama and Ohio State,” Brohm said. “Rightfully so. They’ve earned it. They’ve got great players, great talent, extremely well-coached.”

Ohio State is a perfect 7-0 on the season and has marquee wins over TCU and Penn State.

In the last two games, the Buckeyes have struggled with putting away Indiana and Minnesota, as both opponents were able to make things difficult for Urban Meyer and Co. But Brohm was impressed with the way Ohio State found a way to win more than seeing it as a sign of weakness.

“The thing that really impressed me the most about them, they’ve had a couple games that have been a little bit close and these guys just know how to win,” Brohm said.

Purdue (3-3, 2-1 in B1G) has won three straight games since starting the season 0-3. One of those wins came against then-No. 23 Boston College. But the Buckeyes are an entirely different animal.

Brohm understands that Saturday will be the biggest challenge since arriving in West Lafayette and it’s a huge opportunity for his team.

“They’ve got a lot of history and tradition,” Brohm said. “It’s going to be a very tough matchup.”
