I think Pemsl will be a badass Hawkeye when it is all said and done. He and Cook went at it the 3rd game of PTL and it was a good battle, with Pemsl's team winning. Cordell is a ballplayer, no question.
As Rob mentioned, his handles are great. I would not be surprised if you see him taking the ball up the court as a point forward on occasion. Do not be surprised seeing him lead the fast break down the court, or throwing it ahead for an easy basket. His passing & vision are very good.
Cordell will contribute as a freshman. I suspect quiet a bit. I have him pegged as the 2nd most important (true)freshman this year. He might not be 2nd in minutes(I have a feeling Jordan will get quite a few minutes at backup PG), but his value will be 2nd to only Cook in what should be a (hopefully) deep front court... He will have a memorable Iowa career. Count on it.
