Iowa defense struggling early in Big Ten play Associated Press Copyright 2013 Associated Press. All rights reserved. This material may not be published, broadcast, rewritten or redistributed. Updated 5:19 pm, Wednesday, January 9, 2013 McCaffery has put the onus on his players to shape up ahead of Thursday's home game against No. 18 Michigan State (12-3, 1-1) or changes could be coming. Granted, the Hawkeyes play an up-and-down style of offense that tends to lead to high scoring games. Michigan shot 58 percent from the floor, had four times as many assists, 24, as turnovers and scored 17 points in the final three minutes of the first half. Michigan guard Trey Burke and forward Glenn Robinson III earned weekly Big Ten honors in large part because they posted double-doubles against the Hawkeyes. The Hawkeyes were hopeful that they had moved past the nights of porous defense that shaped so much of last season. [...] Iowa has allowed 95 points in each of its two true road games, losses to the Wolverines and Virginia Tech.
