What do you think about the Andrea Bargnani trade rumors?

I'm a Raptors fan and I'll admit Bargnani is my favorite player. Still, I don't see any justifiable reason for trading him. He averaged 21 points this year and was by far their best player..yes Derozan was good, but he hasn't become a complete offensive player yet. Most Raps fans just want the team to build around Derozan and Ed Davis, but how would the team be any better? Bargnani is playing out of postion obviously (should be at PF) and that hurts the team. They should trade for someone like Marcin Gortat who can rebound and defend and allow Bargnani to play the 4. Andrea needs to get better defensively, but offensively he can shoot the 3, drive better than probably any big man besides Dirk, post up and shoot off the dribble. Replacing his offense would be almost impossible so I think trading him would be a huge mistake...what do you think? I do think Calderon needs to go though, and Bayless should start.
