Dream Alliance making jumping fences look easy.

Maybe some day, years from now, some filmmaker will make a heroic sports movie about Tom Brady or LeBron James. Maybe. But most heroic sports movies aren’t about athletes like those two, who are great from the get-go and win lots of championships over long careers.
