Those are two different arguments. If America cared about Rugby then they almost certainly would be competitive due to economy and size of population.
But NFL players would fail at Rugby. People seem to think that Stamina can just be trained for, this is not true. You can improve it yes but your overall level is determined by muscle make up, the percentage of fast twitch and slow twitch muscle fibres you have in your body. NFL players, as has been pointed out by every American on this site, are strong and fast, so probably have a very low percentage of slow twitch muscle fibres meaning that they would most probably be poor over long distances.
Rugby players require very even muscle make up as they need short explosive bursts but also need the ability to run for 80 mins.
I respect all athletes in their sports, the same way i dont think an NFL player could cross over to rugby, the same is true the other way around...
