Being based in Las Vegas will certainly make things easier, as the number of top-flight facilities and fighters available to work with is greater in Sin City anywhere else, but the kid from Oregon will be forced out of his comfort zone and that can have a serious impact on performance.

Look at it this way: staying in a hotel is fun... for a week, max. Sure, the new surroundings and new bed are great for those first few nights, and the excitement of trying something new makes you forget about home, but after a while, all you want is a good night sleep in your own bed, to eat your favorite restaurant, and to hang out with your regular group of friends.

Whenever two teammates agree to fight each other, one is automatically separated from everything routine and familiar about their training. While Dunham will find a temporary home and a good group of guys to work with, it won't be as comfortable as working with Neil Melanson, Ron Frazier and the rest of the coaching staff at Xtreme Couture who already know how he works.

The question of teammates fighting is one I ask in just about every interview I conduct; it's a great topic and one many fight fans have an opinion on, so hearing what those in the industry think certainly makes sense.

One of the most common responses I've heard involves necessity, as in "it's not like there is a shortage of guys at [insert weight class] for me to fight." Honestly, it's hard to argue with that, isn't it?

Evan Dunham isn't the only lightweight out there for Tyson Griffin to fight. Josh Koscheck isn't the lone welterweight for Jon Fitch to faceoff against. Lyoto Machida has other options outside of Anderson Silva and Antonio Rogerio Nogueira.

In the case of Machida, it could be difficult to avoid a matchup with one of his Black House brothers should he remain atop the light heavyweight division for an indefinite period of time. At some point, he could, in fact, run out of challengers and be left with just Silva and Nogueira as options. But until that day comes, is there really a need to try and force the issue?

While all of the reasons and angle above are great arguments against fighting a teammate, the best of the bunch that I have heard thus far has come from Georges St-Pierre. In speaking about the subject with the Canadian Press, the current UFC Welterweight champion had this to say:

So let's say I'm mounted, on top of my friend, and it's time to land this last big elbow that will probably make a scar in the middle of his forehead and knock him out cold and cause him brain damage," he added, drawing laughs from crowd. "No I'm telling it like it is, if he's my friend, I'm going to think twice before I do it. I won't be able to do that to a friend. So that's the reason why I will never fight a friend. I know a lot of fighters who will disagree with me, but me that's my personal belief.

It's hard to argue with the welterweight champ.

Anyone who says they wouldn't think twice about splitting their friend or teammate's head open...
