Yeah, like Indiansrock and Benis wrote, your opponents are very weak. Nothing has changed from 2.0 as far as needing to avoid all 0-27 type teams, whether they're Big Six or not. Actually, once conference play starts, those teams' SOS will improve, which will improve your RPI, but just slightly.
Any Sims you schedule for the following season should hopefully have a lot of Juniors on their current roster, depending on your team's strength. Even then, if that Simbot is with 11 humans in conference, they will struggle.
