It sounds silly, I know, I just want to see if anyone has experienced something similar.
I'm playing as the Bengals, on my first draft I selected a star QB. On his rookie season he played very well on his first game, but he got injured on the second game and missed 7 weeks. He finished the season with 2,363 yards, 16 TDs and 9 INTs. On his second season he finished with 4,394 yards, 42 TDs and 7 interceptions, which was enough for him to win MVP.
I have played only 3 games of the current season, but so far he feels like a whole different player, throwing more errant passes, missing wide open receivers and throwing 3 INTs already. He was a 76 ovr when he won MVP, and he is currently an 86 ovr.
