You keep recruiting top kids whether they've given you a silent verbal, a loud verbal or even signed a LOI. The fact that A) we have our class mostly spoken for, and b) our other top target is local means Ollie can live in Diallo's pocket from now until next summer if he needs to.
So even if Diallo wakes up tomorrow and declares to the world that he's committing, and that he's UConn for life, and that he never seriously considered going elsewhere... Ollie would still be there as often as possible recruiting the hell out of him. And he'd be right to do it.
