Where the Redheads go

In the world of professional sport, redheads are shockingly under represented.  I 'googled' red headed athletes and the only one I'd heard of before was Shawn White. Don't worry though, I've found out where all the redheads go...RUGBY!
I enjoy watching Universal Sports because they show the more unusual sports: ski jumping, track and field,  cross-country skiing, Ironman, gymnastics to name a few. The most recent I've been hooked into has been the Sevens Rugby tournament.
Rugby is like the train wreck that I cannot look away from. When I first stumbled upon it, I was horrified! Here are dude running around tackling each other with out pads or helmets and the worst part is I couldn't change the channel. The rules are a mystery to me. Here is a list of things I noticed that I cannot explain:
-One team scored. They got 5 points. The opposing team scored. They got 7 points. Favoritism? Goals scored by style points?
-Sometimes they all huddle around the ball and no one touches it. Seems counter productive.
-They do a weirdy version of the jump ball. The teams actually lift the players to get the ball, they don't just jump for it.
-They wear short shorts. I guess that makes sense...less to grab onto?
-Penalties??
-Not only do they pass the ball, they bounce it, they kick it, run with it, and it's all legal.

Can you find the "redhead"?

Rugby is a manly sport. The players look like they are carved from stone.  It takes strength, speed and stamina...Must be why the redheads go there. I'm pretty sure the All Black's will be callin' me up any day now.
