I thought it was an awful call. Yes it was "intentional", in the same way all fouls in a breakway situation are intentional. But in that situation, Gessell had a guy taller than him, barreling full speed right at him, and he had make to make sure he did not give up the AND 1. At his size, and with the momentum of the offensive player, the only way he was going to prevent a shot attempt, was to come down across the guys arms.
It brings me back to bigger issue, which is I think some our guys do not get the benefit of the doubt on calls, because we look physically weak. If Stokes from TN throws his body and creates conduct it is foul on Iowa, but if Gessell, Oleasani, or Uthoff makes a similar play it is a play on. Same thing with handchecking. Gessell gets arm-barred all day by more physically imposing players.
