I watched the whole Cirque du Rudy occur after he was pulled from the game. Either Nate or Monty said something in regards to defense and Rudy walked by with his arms fully extended to each side with a big shrug. He went and stood near the end of the bench, meanwhile Camby went and spoke with Monty after watching the exchange. After speaking with Monty, Camby walked over to Rudy to have a talk, but just before he got there Rudy slammed his towel to the ground. When Camby tried to speak with Rudy, he was pretty much blown off. Rudy never returned and sat at the end of the bench for the rest of the game.
I think he is done, and I think he might even be traded before the draft once we are out of the playoffs.
