And it won't. This is what Mario does.
His first year at Oregon was 2018. They weren't very good...an 8-4 regular season, they had some decent wins, but a blowout loss to a bad Arizona team, barely escaping a below .500 ASU team at home, a really boring bowl game (although they did win). And he went out and signed the best class since *checks notes* ever. #7. Best class in the history of the school, by several spots.
I'm not saying there won't be some decommits. There may be a couple. But this is going to be a very good class when the ink dries. He is quite literally one of the best recruiters on the entire planet, he has the infrastructure surrounding him to compete in this changing NIL landscape, and he will use the struggles to his advantage, to be honest. "We NEED you. Look how quickly you can come in here and play. This last guy had no clue what he was doing. This is The U, you can come in right away and compete for a starting spot. 10% of this roster are my kids, I don't have any ties to any of these dudes. Come put them on the bench." etc. etc. etc.
