Arkansas-Little Rock: There isn’t much that is flashy about the Trojans. But there is substance in what Arkansas-Little Rock has accomplished. Picking up 29 wins is impressive, especially since 12 of them came on the road. The Trojans also beat schools like Tulsa, San Diego State and DePaul on the road and also lost at Texas Tech, so they’ve been tested. Arkansas-Little Rock also loves to dictate a slow tempo, as they’re 345th in adjusted tempo, per KenPom. That slow pace helps the Trojans allow 59.9 points per game, which is third in the country.
That doesn't sound like a team that should beat Purdue. Those 4 schools they played are not the same caliber as Purdue.
The only scary thing is a huge difference in the 3 point efficency, but the Boilers should be able to pull away at some point.
