I think a lot of that is being overstated.
First, I fully expect Bronny to stay in the draft is some team agrees ahead of time to draft him. Will that happen? I don't know, but I'd lean towards yes. Probably the Lakers if that is where Lebron is staying. They aren't winning any championships, so might as well draft Bronny and go full circus. I half joke, but I think Lebron isn't wanting to play forever, so he probably wants Bronny in the NBA.
How is Lebron going to attend a bunch of games? Easier when they both played in LA. If Lebron is in LA and Bronny in Norman, no way Lebron makes enough games to impact attendance. I also don't think OU fans would come out in droves to see him sitting in the stands, considering they can literally see him play in OKC when he plays against the Thunder. Did USC attendance soar this year?
Is there anything tying Bronny to OU other than some list of guards in the NBA Draft that might still come back?
Just seems like a long shot, a VERY long shot, no matter how you look at it. I don't see what Moser/OU/Oklahoma can offer Bronny that would be even remotely attractive to him.
