Does Size Matter in a Fight?

It's not the size of the dog in the fight, it's the size of the fight in the dog!

I can't tell you how many times I've heard that over the years, but is it true? Does size actually matter when it comes to a fight? Personally, I think it matters a lot more than some people would like to give it credit for.

Professional fighting has weight classes for a reason. Size matters. Take Conor McGregor for example. He's no doubt a skilled fighter. He's one of the best pound for pound MMA fighters in the world, but even the term "pound for pound" suggests that size matters. Put Conor up against Brock Lesnar. There is absolutely no question that Conor is technically a better fighter than Brock. However, I seriously have doubts that a fight between the two of them would go in Conor's favor.

Don't get me wrong. Skill definitely plays a factor but the real question is, does someone possess enough skill to overcome the size difference of their opponent. This to me suggests not that size or skill matter more than the other, but that size and skill matter equally. I think rather than say, "size doesn't matter" you should say "Size isn't everything".
