That is true, but remember those teams will be missing at least 6 games vs top 100 RPI teams, including 3 vs Top 25 RPI teams. This will not just hurt them because they won't have them in the conference, but it will hurt them because their RPI will suffer by not playing games vs those teams.
That is 6 games vs Top 100 RPI teams you will need to replace to keep your RPI near that number. Their saving grace is #20 UCA, if they can continue to play near that level. But there will be a significant drop off from #1 - #2 now.
