I'm not a sports fan, so my knowledge of games is sparse. Volleyball is waaayy down on the list.
However a couple of the grands play. And one of them gets her name in the paper for every game. She's GOOD!
So, dumb me can figure out what an Ace is, and I suspect an Assist is helping someone else get an Ace.... But what is a Dig? A Block? A Kill( I think I know that one)
