Simpson was thrust into a very difficult roll 4 games into his college career. He's going to be fine. If you can't see that, I don't know what to tell you.
The other 4 experienced starters shit the bed in the first half. I'd be more concerned about them. Part of their job is to help a guy like Simpson. They looked just as lost as he did. Concerning...
Omoruyi/Hyatt/Mag are not guys who run the show on offense - they are the recipients of guards who run the show. Spencer has experience overall, but not with our team in our system - this was his 4th game gelling at live game speed with these guys, and he's primarily an off-ball player.
Simpson will be good - but he wasn't ready to shoulder the load he was given today, and neither was Miller.
Our season this year will go as Mulcahy's health goes. He's a tough kid, and a sacrifice-the-body player... but he has to be smarter this year and not put himself in as much risk, because there's too much fall-off for the offense when he's off the floor for extended time.
