The people who insist players should go are as bad as those who insist they should stay. It's none of our business to say what they should or shouldn't do or what their motivations should be. Everyone thinks that money should be the only motivation, and while it sure as hell is important, its not necessarily the only motivation for everyone. Clingan (and Castle for that matter) are somewhat unique cases where they and their families seem to value college as more than just a stepping stone to a pro career (and have some financial luxury to do so). If they didn't, Clingan wouldn't have stayed in Bristol as someone else mentioned, and Castle would have gone to Kentucky or Duke or something. If either of them wanted to stay because they and/or their families felt another year at UConn would benefit them more on a personal level, who are we to criticize. And with NIL and insurance policies, yes, you could argue there isn't as much of a rush anymore to jump as soon as you can. Yes Danny should lay out all the reasons they should leave, but he shouldn't dismiss any reasons they may have to want to stay.
That said, yeah, I think they should both go, and probably will, but that's just me and what I would do. I'm just not going to presume that's what's most important to them.
If they did decide to stay however......wow. How would they not be the favorite to win it all again?
