Unfortunately with no player editor for the PS3 version it's difficult to get all the player ratings correct especially when you just wanna fix one stat like focus for WRs or TEs. Something you can try though is to add/remove stars for offense then check the depth charts to see if the players you want got the correct stat boost. This will redo all the players stats for the team though so you may need to reorder the depth chart to get the correct starting line up.
