I've found myself becoming quite a fan of UFC. I'm still not nearly as big of a fan of it as boxing but boxing just doesn't have as much to take in and even it's marquee events (like Pacquiao v. De La Hoya) don't live up to the hype.
I don't like how in a really short period of time it seems that someone can become the "world champion" in a weight class (see Brock Lesnar). It makes me think that the difference between being good and being great is not quite as noticeable as it is in boxing which makes it sort of hard to follow. Then again, it's not much worth following boxing now for it's "stars".
Quick name me 5 boxers you would pay big money to see (Pacquiao, Margarito.....).
That being said MMA is not about the injuries or the blood sport. There is legitimate, interesting technique to it (not quite the sweet science of boxing but also more complete) and the people who run the sport are interested in keeping the fighters as safe as possible. That being said, there are injuries.
In a recent fight, Corey Hill was injured and this picture is one of the grisliest I've ever seen...ouch! (How's this for a thoughtful post with the veiled objective of showing a gnarly picture?) :)
