this is something i did before the ai fixes started to pop up here and i just tried it again with pdub's ai fix and the results were pretty good.
in the plays.dbf file go to the p1,p2 and p3 columns to the far right and delete the pg from every play that it appears in.
if you do try it or have tried it before please post if it made any difference and what aiact you are using, i'm pretty satisfied with the results i get but someone may get even more realistic gameplay so it's worth knowing just in case.
