the rules of rugby union should allow for more dynamic play than the other full-contact field football codes (american football and rugby league)
in those other codes the ball is dead at the break down - not so in rugby union, and you'd think that would give rugby union an edge in watchability
but right now, amazingly, i'd rate both the NFL and NRL as being more dynamic, at least how the game appears on a screen
i watch a lot of the NFL and NRL nowdays, they are constantly tinkering with their "product", trying to ensure it "flows"
rugby union is trying to do the same thing i guess - but it seems every alteration they make, it gets even more stop-start
makes for an annoying watch, probably still ok to actually play tho
