Who hits harder football or rugby?

There are big differences between Rugby and American football. In rugby, all players are allowed to handle the ball, but the ball cannot be passed forward. The ball can be kicked forward in an attempt to gain better field position or to catch the other team unaware. Also, unlike American football, there is no blocking allowed in rugby. No player can shield or protect the ball carrier and the ball carrier cannot run behind his own players in an attempt to shield from the other team - doing so results in a penalty. If the player is tackled, play does not stop, as rugby is a continuous sport. Once tackled, the ball carrier must immediately release the ball. A penalty will be called if a player is tackled and does not make an attempt to get away from the ball. As the rugby tends to have non-stop action, players must be equally skilled both offensively and defensively.
