I'm not sure what BYU's options are but bringing up a stretch 4/5 that is ready to play day 1 should be a priority IMO.
Along with developing Childs as a 3 point shooter.
A Noah hartsock type that can spread the floor would almost singlehandedly fix our offense assuming we utilize the right scheme.
I think it would help us with ball movement--which IMO would contribute to more team effort on defense.
Also need to address backup wing positions.
