I am generally positive, but there is virtually no way Toledo or Ohio get in without winning the MAC Tournament.
Unless you are saying that the league is too balanced and neither team will distance themselves then that's just flat out wrong. It may be unlikely but either could be at large worthy with a huge run in conference play, especially Toledo. The Rockets currently have a 15-2 record with 14 regular season games to go. If they end up with a 15-3 conference record and then lose in the finals of the MAC tourney that would leave them with a 28-5 record. Their RPI would be in great shape.
The league has had several years where it could have had multiple bids since the last time if the league champion had just lost in the tournament. But those teams won the tournament and hence no extra bid. Too many people confuse multiple bids to mean two or more teams that have at large worthy resumes. All you need is one.
Do I think either will earn an at large? No, but it's not impossible. But either team would need to really crush down the stretch and there are too many good teams in the league this year to make it likely.
