I read something about his year so far recently. He's evidently (up until last night anyway) having a worse shooting year than last year, but his defense has evidently been excellent. I seem to recall he's had some back issues so maybe that's part of the shooting issues.
Aside from chronic injuries, I don't see any reason why he'll sort of parallel his Iowa career in that each season he'll improve into becoming all star caliber.
I just hope his brother gets out of Portland because it's looking like he's not going to get a comparable opportunity at PT any time soon (at least this season for sure).
