In limited minutes he has performed well for the Raptors. He reminds me a little of Amir, someone who can develop into something special, given more minutes.
Why doesn't BC re-sign the kid in the offseason? He's a big body that cuts down on drives to the basket significantly, is high energy and has a decent shooting game. He's not an elite shot blocker or rebounder, but isn't a defensive liability either.
Honestly, a front court of Bargnani, Amir, Ed, and Ajinca with dorsey as the 5th big, will be very, very good going forward.
