LMFAO
Every player on a rugby team has to understand how to pass, kick and advance the ball strategically, has to have the conditioning to play two 40 minute halves with almost no stoppage of play or substitutions. All the while sprinting, tackling and scrumming and to do it well on the professional level takes an athlete with an impressive I.Q.. Hell, there are guys playing in the NFL that couldn't pass a 6th grade English class and the ones that can couldn't run 5 plays in a row without a 45 second break much less a 40 minute half. An average RB from the NFL would never see the field for a European League rugby squad for two reasons. The game changing mistakes they'd make by not having the experience needed that only years of play could provide and the lack of conditioning that would make a Navy Seal ring the bell during Hell week. Football gives you a playbook. They draw you pictures on what to do every play. LoL It's obvious that to switch sports will be hard to impossible either way on the professional level but there isn't a handful of NFL players that could match up with the combination of physical athleticism, intelligence and mental stamina that the elite rugby player has to possess.
Not even close.
This kid could learn to play football in a year.
