The internet is a powerful tool.
“Inverted W” and “Inverted L” are now common terms. Not sure how much bearing they should have with regards to injury prevention, but I’m amazed at how often these terms are used as gospel.
As JD said, I’ll “Inverted W” all day if it gets me to the bigs. Who wouldnt? What if changing your arm action to become “safer” lost you 5 mph?
I don’t think anything tangible came out of the Mitch Williams “expert” video. Pretty generic.
I think Nyman used to say something along the lines of “you can only see what you’re looking for.” Basically, 3 different people can look at video and see 3 completely different things.
Lincecum is everyone’s favorite example of powerful mechanics, but I’ve heard so many different opinions on how he does it
I’ve heard coaches say:
He has great balance
He has a quick arm
He’s a natural freak
I’ve heard “experts” say:
He has great hip/shoulder separation
He produces great torque
He has a long stride built up from great momentum
Mitch Williams said:
He doesn’t move down the mound until his leg reaches maximum height.
Is all of this true of Tim Lincecum? Probably (except for Mitch’s comments)
To sum it up:
Every “guru” or expert can make blanket generic statements either because they don’t know better, or they’re trying to spin things to benefit their own product.
