You cant pass up great talent to satisfy a need. Toronto needs someone to back up the 3 & 4.
Bargnani WILL play center if Toronto drafts him. He weighs ~250, is tall and can block shots (led his league in that category), and, while his upper body is skinny, his lower body is where the real meat is at - making him hard to push off the block.
Since when was he a low post player?
Give me Aldrdige over Bargnani.
