||Football does involve the foot propelling the ball many times a game,
To begin with, a football game starts with a kickoff, where the placekicker kicsk the ball to the opposing team.
Most turnovers involve kicking the football, eitehr by the aforementioned kickoff, or by dropkicking the ball, we call that punting.
Finally, many points are scored by kicking, either one point after a touchdown, or three points for a field goal. On many teams, the kicker is the highest scoring player.
Rugby is nice enough, for a frenetic, thoughtless, brute force kind of game, but I prefer a more intellectually challenging sport, with hundreds of set plays, many specialized positions, and space age materials encompassing the players and covering the field for an almost cybernetic, stimulating experience.
I do believe the NFL has a European contingent, perhaps you could watch a few NFL-Europe games to develope an appreciation for the game, understanding that with all things that exist in Europe and America, the European version will be smaller, cheaper, older and less interesting.
