Stating an OK player is good enough to be potential starter on a playoff team is not saying much in my opinion. Many playoff teams have holes which can be improved upon by bringing in a marginally better player.
Is Amir a finished product? No, in my opinion. I believe there is a good chance his ceiling is higher than what he has shown in 2010-11. Is he good enough to be a starter on a number of playoff teams? Not at this stage of his career in my opinion but I am not certain I will provide the same answer in two years. My guess, and it is just a guess, is that at worst he will be good enough to be the first big off the bench for most playoff team. Very useful player and I see no reason to trade him at this time.
Is Andrea a finished product? No, in my opinion, his stats are nowhere close to constants or incremental progressions/regressions. He has non-standard skills for his position (whatever that is) and that makes it more difficult to project his progression. I think he will play a significantly role for a team who needs his specific skill set for years to come, be it with the Raptors or another team. I would not be so quick in pulling the trigger with him if I was Colangelo because none of the projected 3 (or 4 if one believes the Alabi spin) have yet shown the ability to create their own shot or being good scorers. I am not saying the Raptors and any other team absolutely need a good scoring big man, just that I would be hesitant to do so before it's clearer how the other bigs will project.
