After experiencing some significant issues on defense, Iowa is now seeking to fix its struggling offense Friday when Penn State visits Iowa City.The Hawkeyes (12-7, 3-5 Big Ten) had won five of their last six games before enduring a three-game losing streak over the last 10 days. First, they surrendered 99 points at Southern California and 94 points at UCLA as they returned from California without a victory.Home cooking didn’t prove to cure the team’s ails either, as Iowa dropped a 72-67 decision to Minnesota on Tuesday. The Hawkeyes scored only 28 first-half points and they finished 3-of-21 from 3-point range.”I do think we quick-shot the ball again when we got behind,” Iowa coach Fran McCaffery said. “We were forcing some threes there. Some things might have been different with regard to those particular shots. I would have preferred to see a little more ball movement there, like we saw at the end.”Owen Freeman and Payton Sandfort scored 21 points apiece for the Hawkeyes. Sandfort added 10 rebounds to notch his first double-double since opening night.Meanwhile, the Nittany Lions (13-6, 3-5) have generally fared well offensively — they rank 17th in the nation in points per game (84.2). But defense has been a different story for Penn State, which allowed an average of 85 points during a four-game losing streak prior to Monday’s 80-72 win over Rutgers.
