I think the math of MLB and other pro sports slips by many of us. Today there are twice as many teams in the National League and almost that in MLB as there were in the 50s and prior. Factor that and the expansion of pro sports in general has resulted huge dilution of talent available to MLB. What does that mean? What is the result? It means that facing lesser players 50% or more of the time pads statistics of the better players. That and only pitching 6 or 7 innings a game with 4 or 5 days rest diminishes the super GREATNESS of those super E.R.A. and other pitching stats. More players mean more injuries which dilutes the entire pro talent pool even more. Football nips many potential pro athlete's careers in the bud even at the HS level.
