Agree with you on the Noah comment, Kanter does seem to be more developed entering the league. Noah was not, in terms of body and maturity, however his mobility, desire and pedigree were never in question, also its nice that he took defence a lot more seriously earlier in his career than offence. Many young players just want the glory at the start. Noah has invested his time wisely and made himself into a highly sought after commodity.
As for Noah, I knew he would be great after watching the NCAA tournament. The off court distractions that were going on in Chicago made me lick my chops and push for an Andrea Noah swap. (This was back in the Andrea stretches out defences period) I was attacked mercilessly for wanting to destroy team chemistry by bringing in a headcase. LOL.
Often, NBA ready players come at the cost of future upside. The Raptors should shoot for highest ceiling available, unless... this kid really is 10 rebound capable. If he is, I understand your fascination.
