The day someone comes up with a convincing argument that a player's 10 teammates are significantly more important than his 11 opponents, is the day I'll stop using SOS.
There are some problems with predicting SOS, but it's very important. SOS plays a much bigger role in the final fantasy standings than most fantasy players realize IMO.
That isn't what you're weighing though. The issue you are really discussing is whether his 10 teamates are more important than how his 11 opponents did LAST YEAR.When Doug checked the numbers, this year's SOS calculated using last season's results doesn't have a correlation to how teams do this year.
If you could tell us now what a team's 2006 SOS is using actual 2006 results, that would be worth including in your predictions as a significant factor.
We're not in disagreement here. If you could tell us now how a player's supporting cast will be using actual 2006 results, that would be worth including in your predictions as a significant factor.If you can predict SOS accurately, it's very important. Whether or not you can do that is another story. Lots of fantasy players aren't familiar with defenses, so they're going to rely on old (and bad) data. That's fine. But if you know a lot about defense, that's a useful tool that you can't ignore.
I suppose that's the question then. How well can you predict how a defense will do next year?
Yeah, that's the big question. I don't think I'm as good at it as I was in year's past, simply because I watched a lot less games this year. But guys like Rudnicki and Henry know what they're talking about when it comes to defense.Pretty soon I'll come out with (at least) three articles focusing on SOS. I'll be able to expand quite a bit on my ideas then.
I think a statement that most people would agree on is this:
If you have a QB that averages 10 FP/G, and the league average QB scores 15 FP/G, and he plays a D that allows 20 FP/G to a QB, he's just as good a start as a QB that scores 20 FP/G but is playing a D that allows 10 FP/G. I don't think many would disagree on that (assuming things like playing styles of the QB and D are similar, etc.)
The question then is how much do you weight the D for predictions, since we don't
know which Ds will allow 10 and which Ds will allow 20. (Of course, we also don't know which QBs will score 10 and which will score 20).
Let's say you project QB A to score 20 FP/G and he's got the hardest schedule ever (average opp allows 10 FP/G to QBs). QB B is the reverse, with you projecting 10 FP/G (before looking at anyone's schedule) and a D that allows 20 FP/G.
If you believe your ability to project Ds and QBs are equal, you should project them both at 15 FP/G. If you believe you're 4X as good at projecting QBs, then you should project QB A at 18 FP/G and QB B at 12 FP/G.
