I understand why some folks want to joke about this, that's fine, but I also am thrilled that OP is taking this seriously enough to ask the right questions. For this game, more than any other in my memory, the choice of human player (Pilot) is critical, and not all students will be able to take on the role effectively.
My list:
- Above average athleticism
- Spacial awareness
- Visual acuity
- Reaction time
- Communication skills
- Game rules memorized
Individuals who meet these requirements might be found on basketball teams, ultimate frisbee teams, theater or dance troupes, etc. I recommend narrowing down a list of potential Pilots and getting them into training ASAP.
