it was Pup Whatley and Malcolm Stewart. Pup is the one who crashed..
you gotta scrub if you wanna go fast, just like the bikes have evolved so the tracks changed, so has the riding style. everyone wants to go faster thats how you do it. these guys already rail every corner as fast as possible, they pin it down every straight, so where can you shave time? by keeping the wheels on the ground or getting them on the ground asap. I.E. scrub it!!!!!!! and no one can scrub like bubba, hands down the fastest man to ever ride a dirt bike.
