Football players have more than short bursts of power, they have to go all out on every play, running, swim moves, spins, scratching, fighting, punching, diving, running some more, then huddle for a few seconds and do it again 50+ times a game...they do have remarkable endurance as well as power and agility.
To say football players only have short bursts of power is not accurate; and would only be stated by someone who never played football.
Now, the question is which sport has the "Superior Athletes", Football or Rugby?
If you play Rugby you think you are superior because you run the whole time with no break.
If you play ball then you think you are stronger and more athletic, just because rugby players do not dish and receive BIG TIME HITS as in football.
I know they hit, but not like a line backer blind-side a QB with a 15 yard sprint, (lawerence Taylor vs Joe Theisman) or a punt returner who catches the ball and gets his ass knocked out by a Special Teams Missle.
Obviously, I am partial to football players, but both Rugby and Football have Superb Athletes. The games are different and the games are similar, but neither can say they are superior... IF I HAVE to pick ONE...
I go FOOTBALL!
