In the WWE, there are some reasons why speed matters, like if you're slow, and a 400-lbs-guy falling on you, you can't avoid that falling object, whereas, if you're fast, you can avoid a LOT of pain, and 3-to-5 hospital years! Also, if you're a light guy, and you're facing a big, powerful guy, you just lost your only chance of winning, so, if you're not strong, you gotta be
Pretty fast to be able to win, so yes, it matters.
