Who do you target this late in the game? Before the BTT, Wilson wasn't considered a serious threat to leave early. Not a lot of feasible options that are gonna be able to contribute right away. Even if Iggy reclassified, there's no guaranatee that he's able to contribute right away.
And you can't just take anybody. You have to weigh how an offer will play out. If grad transfers fall through, do you give a scholarship to a Colton Christian type player for four years? It might help you out for 5 minutes a game in year one, but in years 2-4, it's a wasted scholarship that you can't give to a better long term player.
