Cam J wasn't getting the playing time in the playoffs because his defense was atrocious, and because he was getting bullied off the court. He really needs his time to come at the 3 at this point, not the 4.
Meanwhile, Nader is 3 inches shorter than Craig. It's a stretch to play him at the 3. It would be beyond laughable to play him at the 4 or as a small-ball 5.
When was the last time a 6'5" shooting guard played center in the NBA?
Say you don't watch Suns games without saying you don't watch the actual games.
What a joke.
