With that class distribution, unless your FR is going to be a key contributor, do this.
Set practice plan to Motion 20 or 20 plus minutes....Run triangle in games. At some point towards the season when your starters and key bench players have working knowledge of motion, set the Motion into game plan in blow outs. You will get emails asking why from your assistants do you practice an offense and not use it in games, but just disregard.
You will be ready for full implementation for next years, and if you have high GPA guys before this season ends.
That is just my two cents worth!
