Well, at the risk of being "contrarian" I go the other way on this. Look at the stats in that league...the hitters completely dominated in every way. Every team was putting great pitchers on the mound, and they were all getting killed. My guys all had ERAs 2.5-4.0 runs above their actual. It would have really sucked had the fatigue penalties been even more severe (and the league even more dominated by the hittiers.)
My problem with the SIM is that fatigue hampers performance too much, especially for pitchers. I would like to see the penalties relaxed, and would actually like to see the balance of the SIM tipped a little more in favor of the pitchers. Too many hitters outperform, at every cap. Too few pitchers do.
