Very well done, I really enjoyed reading Jaon's thoughts. It would be interesting to know how many more leg kickers there are today vs. ten or twenty years ago. Might be a reason for all the HRs as well as a reason for all the strike outs. In Altuve's case I think he actually uses his size as an advantage. Not sure a tall guy could have the same success with the same approach.
Anyway, we see a lot more leg kickers today than ever before from Big Leagues to Youth Baseball. And no question that we see more power than ever before.
As much as I like Altuve, he has a team mate that I like even more... Carlos Correa who I believe was 22 years old this year and already one of the best players in the game.
