I am not one to base my fantasy season on a player's strength of schedule, but I can tell you right now that some strength of schedules are better than others.
If you take a look at your run-of-the-mill strength-of-schedule (SOS), you'll often see numbers based on records or points scored. For fantasy, that is absolutely worthless. For the most part, we don't care who wins or loses; we just want our players to score lots of pretend points.
So what I've done is broken down how each defense performed against each position last season. The narrower and more precise the numbers are, the better they will move over to this season. Of course, the numbers won't be perfect, because there are too many offseason moves to account for
