Here is a very brief story that I think may shed a bit of light....
Had Pioneer at KV JV this fall.
Pioneer showed up w/ 11 players. 11.
KV, maybe 25-30.
Middle of game, a Pioneer player gets injured. Now Pioneer is playing w/ 10.
KV beats them soundly. Week 3 I believe. VERY hot Saturday morning on the turf.
Pioneer was playing as hard the last snap of the game as they were the 1st snap of the game.
