BYU should be a slam dunk, but 3 big issues. One is the Big 12 would double their Longhorn Network network problem if they bring in BYU's network. Two is BYU's no Sundays policy. Easy enough to schedule around in the regular season, but if you bring them in for all sports, you're going to have to schedule every conference tournament you play to end on Saturday. And three is geography. The conference already spans 1,500 miles. Do they really want to make it 2,000? I could see BYU as a football only member, but I don't think they get in as a full member.
