I would try motion if I was you.
With my team in a motion my three small players shoot the most.
While for princeton my PF gets the amount of shots, my pg gets.
So for me, Motion, PG,SG,SF shoot the most.
For Princeton, SG,SF,PF shoot the most.
So for me, Motion works better against a 2-3 zone.
Run and Gun, has one downfall in my eyes that it shoots too fast. So there could be still a defender on the shooter, while in a motion, mostly they will play one shooter free.
Good luck and I am curious what you will do and what the result will be.
Only in the dark, we succeed!
