Hell yeah, genetics matters. Both Bolt and this chick are genetic freaks. Just because you may not have been given great gifts does not mean others are not either.
Bolt is no freak, just a tall dude running the shit, remember him before, you don't do you? This girl isn't one either. Look at the video, her father is her coach, which means he has a vested interest in her. Also, the Seattle-Orego area is well known for top track programs. Dude has many daughters and all do sports, which means he is living life vicariously thru them. Just like lil Hercules father and that bbing kid and that kid who can gymnastics, the fathers push them. And this father has access to the best "gas" and trainers. Look at the vid again and hear him say, "Im coach", anytime someone says that, they are LYING to you. Destiny's Child's manager was Beyonce's father, he had said that he treated all the girls like daughters---when the smoke cleared who is the one who was the lead lead singer, and who was promoted as beig the prettier one, when Kelly Rowlands was obviously the prettier one? And who has had the better solo career...Beyonce, due to her dad.
I point this out to say, that girl's father is far more than "Coach", and he will do what it takes to make her seem like the fastest girl on earth--while playing the "slow white girl" angle and "genetic freak" angle, just as she stated in the beginning.
Just as they have done with Bolt. "Oh, he's a genetic freak!" No, he is just a tall dude with a long stride... It amazes me how y'all allow yourselves to be pimped constantly...
Just like those dumb Aussy scientists claiming that ancient aboriginals could run as fast as Bolt, based upon footprints, and people believe that shit.
