Defense has been a problem this season for the Iowa Hawkeyes and a lack of it cost them in their Big Ten opener. The Hawks could not get enough stops at crunch time and Purdue escaped Iowa City with a 79-76 win. Robbie Hummel led Purdue with 16 points. Iowa Coach Fran McCafferry says the Hawkeyes need to find a way to defend the dribble drive. Roy Devyn Marble led Iowa with 17 points and Melsahn Basabe added 14 as the Hawks fall to 8-6 overall.
