Roncalli anchors down at #1 in the Boys Z-Ratings — the gap at the top is real. The 5th slot is tricky, but Franklin Central earns it heading into Saturday play. Full Z-Ratings at indianaprepvolleyball.com

Boys ratings are updated. Keep in mind that if you have less than 3 results that we've seen so far, we've hidden you from the ratings (we're looking at you Roncalli, Homestead, Lutheran and others). Enjoy. indianaprepvolleyball.com

If you are into NCAA mens volleyball and don't think the sport gets enough ratings love (that's what we think), our Z-Ratings (we think they're pretty good) have been updated. Let your friends know. TELL THE MESSAGE BOARDS! zvolleyball.com

NCAA Men's fans... Our algorithm for BRACKETOLOGY. Given the new format, we figured we'd take what we know about the selection process and apply it to our Z-Ratings. Love it or hate it, enjoy (hate enjoying is a thing 😎). zvolleyball.com
