One one side, you have guaranteed money (if you actually get picked where you're projected). On the other side, you get a guaranteed fun senior year (if you avoid injury) and become the all time leading scorer in Iowa history. You have the chance at a conference championship and a deep tournament run (one you got robbed of this year) and you are still pretty much guaranteed the same money you passed up last year. Hell you even have a decent chance of improving your contract.
I just know a lot of guys leave early and don't end up getting drafted where they hoped, if at all. I'm sure a lot of them are still ok with their decision. But I'm sure some regret it too. A guy like Luka is giving up more than most by not coming back. I completely get it if he leaves. It would be really hard to wait on that much money and that dream. But to say "you have to leave" means you don't get it if he stays. That's being pretty hard on someone if they do in fact decide to stay.
