I bellieve others have asked about this same thing in the past. Im not sure if any managers have been in trouble though. From what I gather, the other team's players' skills are visible because the add on stores the skills from when the players were on the TL. So some skills make have changed for players. Its almost like if you go in the the TL and write down all the skills of every player. You would obviously then have an advantage over others. But this add on just does it for you. I feel this would take away from the game though.
