 Yeah, so that's a great question. So in a seven-on-seven format, you can put some girls in near the center to sort of block. And what blocking is in girls like football is kind of a screening. There's not contact, if you will, from a traditional standpoint of a block in football. So they can get in the way of someone who's pursuing your quarterback over the course of them trying to drop back and make a throw. So you can put some girls in there near the center. You can have them get in the way. Or you can just design your plays.
