As far as level of intensity- maybe you aren't playing with/against the right teams. If you ever get the chance to step on to the field against a really competitive team (I know there are a few of those across the state), let me know what that feels like.
I love watching football. I follow my school to every home and away game - preseasons scrimmages, regular season, and post season play off games. It's an awesome game to watch. One reason I love watching so much is because I can no longer play. It is a physically tougher game than soccer. Not to say soccer isn't tough, football is just tougher. I still play soccer and love it just as much. Something about the game that I just can't place, but it is really a great game. As much as I enjoy both games, I'm going to have to agree with what a handful of people posted earlier, football is the game to watch, soccer is the game to play.
