Everything evolves. If it wasn't before, it is now.
The planet earth used to be square.
The "I have watched two more decades of baseball than you" argument is a poor argument to make when referring to baseball knowledge.
By that statement, that century of baseball also defines Brian Cashman's and Theo Epstein's regimes as GM's, and lots of people here have also watched two decades of more baseball than those two.
Times change, baseball has changed, and while there are useless stats, i just don't see how you can argue that statistical analysis has gained a new level of importance in the current spectrum of the baseball world.
What once was, is not anymore, and what now is, will probably not be tomorrow.
