These really need to be fixed before any trades start being processed. All players should be one year older but some really got messed up. On my team for some reason Latendresse and Backes are 25, Hamilton is 29. I'm not sure how you guys imputed the ratings but there's a quick way to fix this, the positions, remove all the players that shouldn't be there and also know which guys didn't get new ratings.
Let me know if you don't know how because it can be done in about 20 minutes.
