Good article Joe. I think that these stats will take a generation to actually make an impact. Sure, the current pros will look at them and use them, but it won't be until fans really play with them, then raise their kids in Little Leagues with the knowledge gained from them, and teaching their kids how to use lessons from them, that they will impact the game.
Having said that, I really want them as a fan and think that some neat things can be done with them.
And, having said that, I am still very much a believer in scouts. No stat or machine can tell you what the fortitude and character of a player is, and that is always going to have a much greater impact on their performance than anything else.
