I'd be OK with a .500 min restriction for post-season play as long as you also add a 150 RPI/SOS restriction to go with it. Those mid-major teams that play in near empty conferences would need to play a way harder OOC to go along with their possible cup cake conference schedule to balance things.
So neither of the above two teams would initially qualify and would only get added if no other team meets those qualifications.
By the way, those two teams have unequal records probably due to the fact that Team A lost in the first round of the CT while Team B won 1 CT matchup and lost the second (thus the one more game played).
