I've always been a huge fan of football. Don't see rugby much over here in the States, but the bit I have seen just never caught my interest.
And for those saying Rugby is more violent, it may be true but it's also safer in a sense than football BECAUSE they wear no pads/helmets. Many players get seriously hurt in football not just because of the hits put on them, but because of their helmets and pads that they wear.
Collegiate rugby studies have shown that those who play rugby in college suffer less injuries than their collegiate football playing counterparts. The rugby injury rates were comparable to those of soccer. Also many of the rugby injuries were just broken noses and scratches. Football players suffered broken bones, concussions, etc .
Here's a link to more info on this.
