You can get a yellow card in wrestling too.
I have never and will never play soccer, but **** , those guys are in shape. As good, or better, in shape for wrestling than cross country guys because of 2 things: 1) Endurance like X-country and 2) sprinting, unlike the x-c guys. The best of both worlds.
Maybe Nigel only likes soccer for its health value (hopefully, because it'd be hard to imagine an Abilene foot fairy)
