Both Texas and A&M have one conference loss each, so one or the other is very likely to make the CG, which these days is .... a curious thing. Sit it out and you probably make the playoff, make it and lose and ....... of course you have a 50% chance of winning, roughly speaking.
Losing a CG is a pretty bad thing even if you make the playoff, it means an extra game of wear and tear and a drop to maybe a 6-7-8 seed, or worse. Drop to a 9 and you face a good opponent on the road. Does winning the CG offset the risk of losing? Or are you better off missing it entirely?
