If link doesnt work just go to youtube and search MLB 2K9 Tim Lincecum Video- MLB.com @ the 1:49 point he instructs his pupil to push off the rubber w/ the back leg.
I was reading thru a previous thread re: pushing & Lincecum was the sample choice in reference to push/or not to push.
I ran across this video looking for others that had his father discussing Tim’s mechanics & he clearly states a “push” when describing mechanics & initiating the stride.
I have read Tim Lincecum interviews where he states push as well.
It can be debated as to whether they “think” he pushes vs actually pushing, but no doubt he has been taught & in this case teaches “pushing” off the rubber.
I never felt a push, tried to push or teach to push but I think its clear he pushes when he rotates his right leg over… which he does earlier than most.
Don’t know if this adds fuel or clears anything up, but when it comes to Lincecum my son & I are HUGE fans & we dont try to emulate anything he does. He’s just different than anyone I’ve ever seen (flexibility & athleticism are off the charts) & what he does vs what is conventional or recommended is an unfair test.
