It's possible, but what the OP stated as there are several examples, it happens exactly what he/she is stating. I believe the OP meant to state the example as Pitching Ranking/stats. If the screen comes up again w/ errors such as the OP is stating, I will post a picture. I have seen stolen bases incorrectly ranked and that's a hard one to confuse where the ranking should be...it's in the bottom half (i.e., Offensive stats ranked) and where my controlled team had more stolen bases w/ a lower League ranking than the CPU controlled team; and the other Offensive stats are Ranked correctly.
The OP is correct w/ the observation; it is random and one time it will be correct on a stat ranking, the next time it could be wrong...you can see all rankings correct and you could have one or even several incorrect.
