On a side note, my 5 year old son does a thing called "Sportball" that is an actual company that has coaches do classes through city parks and rec and other things. He learns a whole variety of different sports in a fun but not as structured (like practice) environment. He likes it and it's more like play. He's not totally focused right now and able to enjoy teeball (that was a nightmare lol it's so boring i can't blame him). Eventually he'll focus better, but this is a fun way to introduce it to them.
On topic though, I had a co-worker who'd teasingly call it sportsball. He wasn't horribly annoying, but some who do this make me want to punch them. They're the same people who complain about the people who say they never watch GOT.
