If we have a coach and Monday is the day we announce it, would SMU tell the media about the coming press conference today? If so, then today is the day we would know we have signed a coach. This assumes the mrydel model of Monday the 3rd as the press conference date.
Or, would SMU announce a press conference the same day they have the press conference. It would seem to maximize press attendance, that a day's notice (or longer) would be more advantageous.
