It would be fun if you have a sports prompt contest, but the prompts will just be what kind of sports you have to write about. There are plenty enough sports to cover as much as fifty slots. Great variety too.
F.e. Tennis, basketball, ice hockey, bobsleigh, soccer, baseball, sailing, chess, darts, shogi, cycling, speedwalking, sprinting, biathlon (shooting and skiing), fencing, wrestling, climbing, chase tag, tug of war, wheelchair basketball, blind tennis, dressage, archery etc.
Edit: and this year we also have the summer Olympics. So the timing would be pretty great.
