I think as an assistant, sure. He's smart and played good D - seemed to be a decent floor leader. In no way would I consider anyone for the head coaching job who hasn't been, as a minimum, a long-term assistant with some of the best coaches of today.
But seeing DC on the sideline in some manner sometime in the future would be OK with me.
Would he still signal to Jackie, or would she be sitting close enough to him to not require that?
