Does NBA 2K11 on Wii Support the Classic Controller? No

No. NBA 2K11 on Wii only supports the Wii Remote + Nunchuk combination.

Why

• The game's control scheme is built around motion-based shooting, passing, and dribbling gestures.
• The Classic Controller's analog sticks lack the motion sensitivity required for the game's mechanics.
• 2K Sports did not implement a Classic Controller profile for the Wii version.

If you prefer traditional controls, the PS3/360/PC versions fully support standard gamepads.
