I completely understand that MLB is MLB & WIS is WIS & I agree with the opinion of Joss, Pedro, Maddux, Pete & Matty being better than Koufax & Gibby in higher caps but when you look at the data-OAV+, WHIP+, ERA+, HR/9 I don't see the reason that should happen.
I am about to use Joss, Pedro, Maddux, Matty in a 255 league (no player >$15mm) at Clevelands League park but I chose Joss & Matty because of WIS perfomance history not because of the data that I am looking at.
