I could see NIL money being used by schools with lots of money as a way to boost these "other" sports - such as baseball, which have limited scholarships to begin with, but now with NIL and possibly the ability for the school to pay the players directly - give out more "scholarships" than the NCAA limits.
Example - Baseball.
Roster can be 40. And you can only give out scholarships to 32 players, but most schools give less than that.
So lets say your a school that divides out 20 scholarships to 30 players or more. Giving partial scholarships along the way. Why not now - give those 20 full scholarships to 20 players. And then use NIL money to give money - in the amount of tuition, room, board, etc - to the remaining roster. As a result - you have now fielded a team on full scholarship across the board.
This assumes 2 things - 1) You have the money to do it. 2) You have the mindset from the administration to do it.
On a similar note - we all know the impact Basketball and Football appearances have on school marketing and admissions, etc. Does baseball have an effect? The past 2 weekends - it has been all over ESPN, and it will really get highlighted next week when the World Series starts. I don't expect the impact to be great - but do you think a super regional or college world series appearance has a positive impact on a school?
