That's the catch. While Purdue statistically is one of the worst Football Bowl Subdivision teams in the country, it has also had the nation's hardest schedule, based on opponent winning percentage. So O'Brien said Penn State will not dwell on Purdue's record in preparation this week.
"We don't have any problem focusing on Purdue," he said. "We respect Purdue. I think Coach (Darrell) Hazell is an excellent football coach.
"Our guys are very focused on this game. With our guys it's never a matter of focusing on who the opponent is. It's not. It has nothing to do with records or anything else. It's about playing the best football we can play and trying to get better from the mistakes that we made last week."
O'Brien announced that sophomore linebacker Ben Kline will miss the remainder of the season due to a tear of his pectoral muscle.
Penn State's leading receiver Allen Robinson also injured his shoulder against Minnesota, but O'Brien confirmed that Robinson is expected to play Saturday.
