I really don’t know what to think of Rock. My recollection is Blum saying on pre-season podcasts that we could expect to see him for up to 10-15 minutes/game this year. So one of 3 things happened: Rock underperformed, Chatfield exceeded expectations (or some combination of this), or Blum was given (or was giving) bad information.
Rock doesn’t look ready to me, but we also haven’t seen him in many minutes, and certainly none that were meaningful. But when you realize he’s the age of a true freshman, that’s not surprising, either. I just don’t know how anyone that’s not inside the program could really have a strong opinion about his future.
