Do coaches have an unlimited number of recruits they can bring into the school? Is there a roster limit for preferred salmons at each school? I don’t know the answer. But if it’s yes at any of these schools then this affected athletes. And either yes or no it shows how little oversight there is from the university overseeing the recruits brought in.
It's not stretch to say that the number of students "recruited" exceeds the number that actually show up on the team.
I don't know about "unlimited", but a coach adding an extra one or two to their recruit list isn't going to attract much attention...until now.
