I’d run a Houston style offense. Not as many 3’s, but pass to Hugley, hand/off, fake hand off, dribble at backdoor, hand off, screen, roll etc...
Yes lots you can run out of this after you have the basics down. With the paint being open you have the basic back door on an over play to keep the D honest. And as you said the dribble hand off or fake hand off back door. P/R at different spots etc.
You can run quick hitting pin downs for a shooter like Horton by starting him in the corner spot and if the D is over playing him he can curl into the lane.
When Huggins took over at WVU he actually kept a lot of the O his first year or 2. I remember when Da’Sean Butler would cut down the lane they would have him stop dead mid cut at times and he would seal his man for a quick post up. This action would work for a guy like Justin or Hugley. If it’s not open you just fill the vacated spot on the opposite side you cut from when everyone rotates spots.
