Even in RTG the sim is pretty awful. The Heisman winner my first year was a true Freshman QB from Memphis with good, but not great, stats. The next year it was a DL from Michigan State (congrats @FriendlySpartan) who missed two thirds of the season with injury. In my third season I'm in the CFP with my first game against North Texas, quarter final matchup against UAB, and semi-final matchup against the winner of K-State/Georgia Southern. So I tend to believe the sim isn't great.I’m the opposite. I’ve only played Dynasty and haven’t really noticed sim engine issues. When it comes to value I’m pretty sure I’ve already gotten enough out of it.
Also, playing as a WR, I have to agree with @AirWalke about the abundance of block in the back penalties. It even happens regularly if I don't tough the sticks on a running play and the computer manages to run into the back of some DB. Infuriating.
