Purdue may be bigger, quicker and stronger than Saint Peter's.
But guard Lewis Jackson said his Boilermakers still have to keep their focus firmly on their opening round opponent.
"They've got a veteran group," Jackson said of the Peacocks, who start three seniors. "They fight hard. They're good on defense. They're interchangeable in spots. Their (power forward) can be a (shooting guard) sometimes. I really think they're going to try come out and compete."
Saint Peter's doesn't have a player taller than 6-foot-8.
But Jackson said that doesn't guarantee Purdue will dominate inside.
"We can't overlook their size, look at them like, 'Man, we can outrebound them and outmuscle them,' " he said. "We're used to being in that position with other teams in the Big Ten and other good teams, so I think we just really have to compete and stick to ourselves. But we know they're going to come out and give us a fight."
