In regards to scholarship limits - these are roster caps. For basketball next season, the cap is 15. The language I found online states "These changes will allow more players to receive scholarships, but the teams will have to follow the new max roster size limits". So for basketball - the roster is 15 with scholarships at 15. So you can't give out 15 scholarships and carry two walk-ons to get a roster of 17. What is most likely to occur is you still have walk-ons, probably filling out the roster like before - say spots 12-15 on the team. You probably give them a scholarship (if the school commits to all 15 scholarships), but you likely don't give any payments to these players. Whereas the rest of the roster will get their scholarship and payments from the school under the new settlement.
But - I could see lower level schools, and UR might fit into this category - try to save some money, and say - scholarships and payments to 12, and the remaining 3 are on their own just like before. Therefore saving the 3 scholarship money for payments.
I like that we got a big man on the roster, but in this day and age - means nothing. This kid will not see the floor next year, which only means he could transfer somewhere (although doesn't look like he had any other offers), or UR will likely just need to secure someone in the portal next year with size. The day of developing freshman is over. They either come in and play right away and make an impact, or you will probably never see them again on your team, as they will transfer and play somewhere else.
