Rarely does the NCAA come down on the side of mercy when dispensing punishment.
I can't imagine a scenario that won't end (very) badly for Baylor given the scope of the violations and the length of time over which they transpired. Those elements point to a habitual disregard and flaunting of the rules that the NCAA can't accept.
I would assume the Baylor programs will receive penalties equal to, if not far greater than those handed to the UConn Men. Beyond prohibition from NCAA and/or Big 12 tourneys for "x" numbers of years, forfeiture of scholarships, firings and/or game bans for coaches, the forfeiture of the NCAA championship may not be out of the realm of possibility.
Given part or all of that as a potential backdrop, I don't see how Britney would stay. If she were my daughter, I'd strongly advise her to go pro. This is her time in the Sun and these moments are always fleeting. Britney needs to keep moving forward even (and especially) if Baylor BB cannot.
