Iowa is who they are under Fran. Athletically they will be improved from past years and more so after the debacle that was last year, but you can't change the identity of a team that Fran has spent his 14 years molding into an offensive machine with little regard to defense by the snap of the finger or with lib service.
What are you seeing Iowa improving on in the defense? Other then more steals, blocks, a few more missed shots by the opposition, Iowa isn't going to guard other teams the same way say a Duke, Connecticut, Arizona, or Michigan St guard teams, or defensive minded coaches teach their teams to play defense, that's not Fran and never will be.
Iowa is not going to turn into a Wisconsin type team under Fran, not even close nor would I like to see that, but hopefully games that Iowa struggles scoring points, they can use their athletic abilities to keep other teams from making runs that have all too often caused Iowa to lose those games. That's all I can ask for and hope that this is the season that Fran can break through, challenge for the Big title and make it past the 1st week of the NCAA tournament. I've already said that this team has the best chance to make it past the 1st week of the NCAA tournament and barring injures that will happen with this team.
