Those guys can pay whoever they want or whatever they want, but they aren't the ones who chooses who signs the papers. As to Harsin, I don't think it's a big secret around the auburn program that his stance is to win without egregious cheating. I know that's odd for an auburn coach, or really any SEC coach, but it's apparently a strong sticking point with him. Doesn't mean they don't use NIL (they do of course)... but I don't believe they use a Texas A&M like system either. His stance on that could certainly change, but he'd be wise to be careful at this point so that he doesn't get the Pruitt treatment by the vultures who want to try and oust him free of charge...
