Um ... sorta, but not really. I thought there was a good chance he'd average something like 10/10/2 his rookie year and by year two might be puttting up 14/12/2.5. But after he had the surgery all bets were off as far as I was concerned, especially after the struggles I saw Amare go through in his first year back from surgery -- the guy looked flat out done.
Frankly, at this point I barely even think about Greg this year, it's almost a given that he's going to struggle mightily to stay out of foul trouble and stay on the court. Clearly the fouls have gotten into his head and are making him second guess what he's supposed to do out there, so I just try to chalk it all up to learning the pro game and him trying to get his explosiveness and quickness back (which was bound to take time).
My advice would be to just expect the struggles and then be surprised (and happy) when he has a really good game like he did against Chicago, Boston, etc.
