Again, STDV should not be used as a tool to pick where people get drafted. It should be used as a tool to decide between 2 WR's that you feel are deserved of being picked at the same spot roughly. STDV is pretty much the same as saying I can pick (this is an example and not based on actual schedule) Dunn or Droughns as my 3 RB but Dunn has the same bye week as my number 1 RB, so I'll take Droughns. STDV is more like a tiebreaker if you will.
So looking at the WRs. Owens had a higher AVG score, lower STDV, and lower relative STDV when compared to SSmith. So given the choice, and assuming all else is equal, TO would be the more logical pick. Of course TO is in a different setting this year so his value could change drastically, but you see the point I am getting at.
On the same level, let's say you had the choice between SSmith and Holt. Yes SSmith had a higher AVG score, but Holt had a lower STDV and lower relative STDV. My argument would be that week in and week out Holt would be a more consistant WR. Looking at the hard numbers from Twisteds method, you can see that SSmith actually outscored Holt more weeks than Holt outscored SSmith, but there is not one week when Holt would have cost you a game, which unfortunately SSmith did a few times last year. Yes it is nice to see to 40+ weeks from a player, but we have all probably lost because our stud decided to put up a whooping 5 points or something to that effect.
So I hope the additional charts give a better understanding of what I use STDV for. And it should be said that this also goes along with the type of owner you are. Some owners are more of the gambling type and would prefer the boom or bust type player, whereas some would want the week in and week out performer. And depending on your stance, or stance at a particular pick in the draft, you can use STDV and relative STDV to help make that decision.
Great stuff here... no thunder stolen, whatsoever. I am still going to crunch the yardage st devs for the other positions (including TE), because I think that just conceptually, higher fantasy point standard deviations could result from touchdown variation, which I guess is important, but I always want 10 points out of my players (i.e. 100 total yards) and the touchdowns will come when they come.
I was also thinking that standard deviation may govern precisely which kicker I pick in the last round of my draft since consistency is all I want out of that position.
