i went with TD. With TD you can scale back his responabilities...with MM you really can't. I suppose you could make him a TE coach, but if you are keeping him as a head coach, then he is what he is. nothing will change the fact that he is terrible with time management and play selection.
if you keep TD and let him control finances and marketing and let someone else control all personel decsions that would work for me.
maybe take away his power to decide what signs can be displayed on game day as well.
