To play a 2 point guard lineup, we need 3 point guards who can score on the roster playing sizable minutes. To get 3 playing sizable minutes, you need to recruit one every year, this allows for early departures (as Jalen probably will be after his junior year) or for the 4th PG to develop in a minor role as a freshman.
In general our 2PG lineups have been 1 PG (A.J., Bazz, Tate, KEA) and 1 CG (Kemba, Boat, Ricky, Smitty) better suited to playing off the ball. Those require different skillsets and mentalities.
Quickley can score, has size, what's not to like?
Nothing! I hope we get him, and you're probably right that we could easily play three guards with him in the lineup.
I just hope we're not focusing our efforts there with Chillious, since Shittu is the guy from 2018 that we really need. We were in a good spot with him already, and Chillious has a relationship with him, and he plays a position of need, and he's a top 10 player, and I just think it would be insane to spend our best recruiter's time and efforts elsewhere.
This doesn't mean we stop calling Quickley or anything, especially if he makes it clear he wants us (Chillious) to keep recruiting him. But we need to be smart about prioritization, and to me that means Shittu.
EDIT: let me put it this way: I'm confident in the staff's ability to get very good guards and wings with or without Chillious. I'm less confident about their ability to get quality bigs, so that's where I want him doing work. GO GET SIMI SHITTU!!!!
