According to the Toronto Sun, Casey will be going with an 8-9 man rotation on most nights.
So that begs the question, who do you think that rotation will consist of?
PGs 1. Bayless 2. Calderon
SGs 3. DeRozan
SFs 4. J.Johnson
PFs 5. Bargnani 6. Davis
Cs 7. Amir 8. Gray
That leaves Barbosa and Butler fighting for backup minutes at the wings. Eventually Kleiza will add to that confusion. And we haven't yet mentioned Forbes who's coming in with a fresh 2-year contract.
Then there's Alabi, who we still don't know if he can contribute anything. And lastly, there's Magloire...whose barking in practice will probably lose credibility if he never actually sees the floor.
As for Carter, I think he's perfectly content being a 3rd string PG.
