You are putting words into my mouth throughout your post.
JT did not impress me as much as I feel he could have. He is already 3-4 years older than most prospects who enter the NBA. So yes, it is a big deal if you feel it takes 3 years to develop a big man, since he's already 23. I would much rather have a big man developed at 23 than one at 26.
And our forum is very biased towards JT. I believe during the Amare Stoudemire talks, much of the board would rather keep JT than trade him for Amare, which to be fully honest, would be a stupid move if the opportunity came.
