I play football...
I never understood the whole soccer/football rivalry thing. Pretty stupid. The difference is that the bigger kids play football, and the other kids play soccer. There's no talent or toughness differential. While it's a lot easier to get hurt in football considering the game is made to be violent, you have to be pretty aware of your surroundings in soccer as well.
Also, animal, not anyone can be good at football. That's just flat out a dumb statement. You have to have an admirable work ethic, and get your mechanics down. The small things are much, much harder than people would think. I'm a lineman, take it from me. People who say it's not hard to be a lineman are plain stupid. You have a different responsibility for EVERY play, and you don't always know what you're going to end up doing or blocking until the moment it happens. If your feet are an inch off of where they're supposed to be, anyone will run you over. So, no, not everyone can play football.
The real difference is that an offensive line weighs as much as the 11 kids from one team on a soccer field do. There are 2 linemen on my team that weigh 245, 1 that weighs 260, 1 that weighs 250, and I weigh 255, and none of us are fat and everyone's at least 6'1". Our line alone weighs 1255 pounds. I wonder if the 11 starters on the soccer team combine to weigh that much...
