Playing with broken feet, dislocated shoulders, or especially concussions is just stupid, regardless of the sport.
Thinking about the things people have said they don't like about soccer, some of them are not inherent to the game itself, but aspects of the current game, such as diving, obnoxious fans (Raiders fans LOLed at this), corrupt governing bodies...
When you see soccer being played at the top level it is sublime what those people can do. It is the "beautiful game" as Pele put it.
Indeed, but for many, especially those who have never played it, it can be equally uninteresting to watch.
