As a team that emphasizes offensive, here's a question for you, what kind of defensive would you like to see Iowa play that is any different then what they do now. Take in consideration that Iowa normally doesn't get a boat full of 4 and 5 star players.
Also take in consideration how much energy are you expecting the players to exert playing the defense that you wish Iowa would incorporate. The more tired the players get, more fouls are going to happen.
Really, the more defense you put into the game the slower the game becomes, is that what you want Iowa to focus on. Less offense more defense. You can't have both.
Yes, if Iowa concentrated on playing defense, that could produce turnovers that could result in offense, but that's not Fran's system though. Just like to see your take on it.
Remember one of Iowa's greatest teams, the 1970 Hawkeye's averaged almost 99 points a game and went undefeated in the Big Ten while giving up a staggering 87 points a game. does that sound or look familiar?
