Data for League 2 above: (v6.12) based on role rather than duration
Code:
Correlations: PTal Stuff, PTal Control, PTal Move, Role(100)
PTal Stuff PTal Control PTal Move
Role(100) 0.047 -0.045 0.044
0.129 0.150 0.154 <- p-value
Again, the p-values are greater than .05, hence no relationship. These p-values are _closer_ to the cut-off than those of League 1, which makes me wonder if the fact that League 2 imports rookies from third-party roster makers makes a difference here. I expect that it does.
Bottom line, based on these three leagues, I would challenge the statement that OOTP does not create enough good relief pitchers relative to starters.
The fact that relief pitchers' ERAs do not show the same dip in some leagues as seen in the real MLB world suggests something faulty in the game engine or in the AI. My bet is on the AI, but that is again merely an opinion framed from years of reading logs and gnashing my teeth over odd decisions that I wouldn't have made in various situations.
