The Ivo that abused Julian Mavunga is what I would like to see. He obviously took it as a personal challenge when he was facing him, and he kept us in the game when Miami couldn't miss from outside.
Your thought goes exactly what I've been saying about Ivo. He's absolutely OWNED a few guys down low this year. When he makes a focused effort at getting to the rim, and not using the fade away too much, he's really tough for a lot of the MAC to stop.
