Not going to hurt recruiting.
I don't think it will hurt next year's recruiting much as most have already made up their minds, but one season with no eyes on their programs and eyes only on SEC, ACC, and B12 will start to have some affect on the classes beyond next years.
Any which way recruiting is going to get jacked up with whatever the NCAA decides on scholarship expansions or whatever to make up for giving everyone an extra year of eligibility this year.
