football only members either. Both would be Busch League moves that would further cement the already widely held view that the BIG 12 is the least of the P5 conferences (none of the other P5 conferences have football only members). If the BIG 12 adds football only members, or if they add conditional members, it's a clear sign that neither Texas or Oklahoma are in it for the long haul.
BYU is either in or out. I don't think football only is really an option (unless this is purely a money grab). And, with all of Bowlsby's talk of joining a family, I don't think the BIG 12 would/will do conitional or probationary invitations.
Just my 2C.
