Juulie said pretty much what I was going to say. Very clearly -- without accusing him of anything -- say, "Let's focus on staying in our primaries, ok? If I'm watching your primary, or you're watching mine, then we've got a bunch of kids that nobody's watching."

If you realize during the game that that's not happening, gently remind him during a TO or halftime. "Good half. Let's stay focused on our primaries. . ."

I also agree with BZ that it probably will not be as bad as you expect.
