I agree that the big boys are unlikely to steal our players. But the next tier schools could. They aren’t loaded with talent. As could mid level schools with snake oil salesmen. MD certainly could be a threat for example.
Also a school like Cincy if they wanted to go the Gonzaga like transfer route. If they are Top 15 every year with an outside shot at the playoff, kids could like that. A coach can say you are the guy that puts us over the top.
You also have to account for all the coaching changes that happen. A new coach likely purges the roster and might want to fill in holes.
Overall 1-85 this will be a net positive for us. But those top 1-5 players will always be a threat to leave.
