I-bar, I suspect that you have hit the nail on the head with your assesment of Dom. With his peronality type and what appears to be a lack of an ability to think on his feet spells out a problem as a head coach. Probably a great D-coach, but not a great Head Coach. Nothing against him, just how life works sometimes. To borrow a line from a movie "A man needs to k now his limitations".
