I don't know who all is out there, but I can say from experience that directing live video (ie calling the camera shots) is very difficult. This is true even in a play where you supposedly know who is going where when.
The balance would seem to be 2-3 second closeups at critical moments followed by a return to an overall shot so that people can get re-oriented. The overall shot should be from the same place all of the time so people can stay oriented
It also means at least three good camera operators, a person telling the camera operators what shot they should have, somebody doing the switching, and finally somebody who really understands the game calling out which shots to switch to.
Oh and by the way if these are amatuers, you'd better have at least two complete teams you can swap out. After a couple of hours the first team is going to be fried. Come to think of it for football even the pros don't work for more than a couple or three hours actually shooting. Remember a competition lasts all day and people will lose performance after a while. So it is essential to pace things.
It's been several years since I did anything like this, and the equipment wasn't anywhere near what is probably being used, but I'd be willing to jump in and help out at SJ or LA if somebody wants me too.

Especially if I knew I'd get spelled after a couple of hours or so.
