Tim Lincecum is NOT a freak! He is a pitcher who learned at a young age how to build and transfer energy powerfully and effectively through his body.
They said the same defeatist remarks about Roger Bannister when he broke the 4 minute mile. He was a white Englishmen who loved to run. With a little bit of knowledge of physics and some hard work he did the impossible.
The "Stepover" theory is wrong. Just like when you see a car traveling down the street and the hub caps look like they are spinning the opposite way.
Tim's front leg is flying out to the plate but that is only the effect of the back leg. If I wanted you to jump a bike off of a ramp you wouldn’t propel the ramp under the bike. You would propel the bike over the ramp.
It is called Triple Extension. This is the full extension of the ankle, knee, and hip flexor. It isn’t just about Triple extension it is about the timing of the triple extension.
