Bad defense starts on the perimeter. In the many games Iowa was taken to the wood shed, defensive breakdowns started with our 1-3's not being able to keep anyone in front of them. Whether it was penetration from the top or baseline, Iowa was an easy team to take off the bounce. Conversely, Iowa presents 0 threat to drive it from the 1-3. Moss is stationary. Bohannon isn't a threat to drive. Nunge and Baer take a dribble or two and reverse it out. Our best dribble drive guy was Cook, which should be a clear signal to a coach.
Fran had a chance to bring a juco or graduate transfer in and let them compete for PT. Emphasis on "compete". If this player isn't better or better in situations (teams cranking up ball pressure D) or playing D on a guard others can't stay in front of, then he would not take PT from Connor or Bohannon. I am confident that if you asked every guy on the team if they want to have a repeat of last year or add a guy who might improve the team, they would all opt for the latter, even guys who would see less PT.
