I think we'll have to wait and see what effect this has, if any. It was either do this or see the student-athletes organize. That would have been fun to watch.
Imho, the amount of the subsidy won't make much difference as long as the amount is controlled annually. The real danger would be allowing a subsidy bidding war. As long as that doesn't happen, I think other considerations will predominate for most recruits. It might affect recruits from really poor families, but we'll have to see. I also don't think it will have much effect on Tech; you either decide to come to Tech or you don't on other grounds. But … at this point, who knows?
