Its pretty funny you mention that. Last night I started the third season of my dynasty and my DE got his first sack of the season. There was a stat overlay that said "Season Stats" and the dude had 71 tackles!! I'm guessing it was supposed to be "Career Stats" but still, that's a pretty simple thing that EA messed up. It seems like stat overlays have taken the absolute least priority in the next-gen EA games.
I love to get immersed in every aspect of my dynasties. However, its hard to do so when you aren't seeing the accurate stats of the players on your team.
