JC's body needed a rest. I think it's arguable that his health became too much of an issue for him to continue coaching at 100% like he always did. Now that he's broadcasting and in a low-stress environment, he looks great, but were he to have stayed on the bench I worry about it being detrimental to his well-being.
You may be right about his health - however he pretty has said if Drummond stayed he would have rightly or wrongly - the sanctions made the decision easier for him to retire due to health concerns.
