We could do it with all sports, but it would primarily be the Big 4(Football, Basketball, Baseball, Soccer), plus Hockey, which I throw in because it gives me an advantage, plus maybe Tennis, Golf, no NASCAR, and Olympics. But mostly the Big 4 sports, because that makes thing easier. Plus there are very few people in the world that know a lot about both Golf and Hockey.
