The mid majors and lower will see so little positive change.
Even if more scholarships were allowed, many would not be able to fund any extra scholarship as they are already losing money on baseball. Also consider the coaching staffs will be adding another full time coach with the ridiculous "volunteer coach" going away. These lower level D1 schools will have trouble funding this 3rd assistant even before your broach scholarship increases.
Power 5 guys normally transfer down for playing time, which was a saving grace for these programs, but now the transfer portal is causing the P5 schools to use the mid-majors as farm teams. Should a guy at GaSouthern, Coastal, Gulf Coast, Wichita, etc, have a good underclassman season; there's a 75% chance a P5 school will grab them with NIL the smaller schools and their small donor base have ZERO chance to match.
With MLB contracting the minor leagues, I hoped the majors and their major sponsors would find a way to patronize the college game. So far that has not happened. MLB couldn't necessarily find scholarships or NIL, but could fund salaries, equipment (wood bats?), and travel expense. MLB has basically eliminated rookie leagues. College could take it's place with US players and MLB could create foreign rookie leagues for international players at relative low costs.
