ah.
Spiking is when you celebrate after scoring. If you do that on the ten yard line, rather than in the end zone after scoring, then, that would be the same as turning the ball over to the other team....which is sort of the worst thing you can do in football.
Point being: they are celebrating too early and it might cost them big time!
Wait, so you score on the 10-yard line and then celebrate and then the other team gets the ball? Thanks for the explanation but I'm still confused and obviously know nothing about football.
