I think the new rules will benefit the smaller schools the most. Most large programs have the resources to make the current rules work in their favor. Yes the SEC schools and schools in other major conferences will spend even more money now as harass recruits beyond what they already do but the smaller schools will now be able to fully apply the resources they have which are limited.
Example a small midmajor does not have the money to maximize the current number of off campus visits, but are limited currently by the number of times they can call a recruit. Now they can call a recruit as much as they want with their limit financial resources. Again old rules they had less contact atleast now they can increase contact without increasing their recruiting budget.
