I think you are absolutely wrong on this one. For Moss it looks to me like he needs to learn to pick his spots (much like Jok had to when he was young). Jok would get pulled for defensives lapses, turnovers, and bad shot selection all the time as a young player. Difference was Iowa wasn't nearly as deep back then and Jok simply had to play. Right now Fran has other decent options and Moss will be stuck on the bench until he figures it out.
Right now Moss/Ellingson is much like Jok/Oglesby was. Once Moss figures some of these things out, plays more under control, limits the turnovers and bad decisions he will start eating into Ellingsons minutes. It was obvious even in the short time he played last night that Moss has a skill set that Ellingson will never have.
I am hoping that Moss is like Williams last year, that at a certain point he gains Fran's trust and by the end of the year he is part of the rotation. If that happens he will absolutely be a contributor for 3 years at Iowa.
