I ran some numbers. If Ohio wins out all the way to the MAC title game and loses there (28-5), it would finish around 48th in the RPI. Of course, that's given all things staying equal (all of our opponents performing at their current level, opponents' opponets also and other teams in the RPI playing at about the same level) so it could be a little higher or lower. Losing one other time (27-6) would put the Bobcats around 58th and two losses (26-7) would put the Bobcats at about 69th. Apparently, we're talking about finishing the regular season 24-7, so add one win and one loss in the MAC tournament and the RPI would be something like 77th.
Based on that analysis, I can confidently say if Ohio goes 24-7 in the regular season, it will not get in the NCAA tournament. Really, the Bobcats probably would have to win out until the MAC finals to get into the RPI top 50 and get any real consideration.
