Re: John Dewan: NL Hitters & AL Hitters are equal
That OPS comparison doesn't talk about the quality of the hitters unless you are fixing the quality of pitching as equal as well. If the quality of pitchers in the AL is also better, you could easily have better talent across the board and have equal OPS numbers. Heck, what's the league OPS 1-8 for the southern league or the PCL? If it's higher, does that mean they have better hitters?
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
