I like that even so obvious a departure as Bagley said he was still deciding a couple days after the season ended. I can't think of a Duke player who did it any other way, unlike Ayton and Trier, who announced it in the postgame locker room. I suspect that's coached, that K lets them know how to cast themselves in the best light.
It's surprising then, that Carter is announcing that he is leaving with this level of hype. I would have expected it would just hit the news that he was leaving, not that it would hit the news that his announcement (about leaving) is going to happen later.
