An NFL player would not have the stamina to last a normal Rugby Union game let alone a Rugby 7's match. Although the matches are short (like 14 minutes or something) the intensity is off the chain, they are basically sprinting the whole time and covering massive distances.
Even so Rugby 7's is not where Rugby's best athletes are.
