At the very small rural school I attended in western Pa growing up, we played flag football in place of "real football" for cost and enrollment reasons, and it was still a ton of fun. Emphasis on speed, longer developing passing routes (hardly any pass rush usually) and barely any running game to speak of. I'd definitely want to watch this in the olympics, but agree with others upthread that it's not apples to apples that the NFL guys would automatically be the best flag players as well.
