Iowa has made at least 10 three-pointers in a game nine times this season and is coming off a victory in which it made 12.
Think defending three-pointers is something Purdue worked on this week?
"They have great shooters," coach Matt Painter said. "They have guys that we feel are better than what their percentages show. Sometimes, that's vice versa in college basketball where a guy will have a pretty good percentage, but he's a streaky guy. We feel they're better shooters than their percentages show.
"(Against Northwestern) they proved it by shooting 50 percent. We have a lot of respect for their ability to stroke it beyond the arc, and we're going to have to be with their guys and make it difficult for them to get clean looks."
Iowa is second in the Big Ten in three-pointers made per game (8.2). Matt Gatens leads the team with 47 makes but four other Iowa players have made at least 30 this season.
Senior Devan Bawinkel has made 40 percent of his three-pointers, and Gatens is hitting 35 percent.
Iowa made 6 of 16 three-pointers in its first meeting with Purdue this season, a 67-56 loss.
- During Thursday's practice, assistant coach Paul Lusk was working with big men JaJuan Johnson and Patrick Bade on defending Iowa's ball screens. Typically, Purdue's big men "hedge," but Lusk was telling his guys to be more patient on the initial screen and then not take such a drastic angle when they do hedge. That could prevent Iowa from getting the kind of looks it wants, assuming Purdue follows its assignments.
