seems most people complaining have to be IDP rookies, IDP players just aren't guaranteed to carry their "stud" status like offensive players are, too many variables such as new schemes, new players brought in, etc.i can't see one game where Harris will get 20 tackles again with the additions of jenkins, gholston, pace, those guys might not be studs, but do eat up some of the tackles.
This certainly does not hold true for players like Demeco Ryans.
never said it's a 100%, but you will find way more cases of defensive "studs" losing their values within a year than offensive studs. not saying that some don't carry over, but especially on the defensive side, it's a lot tougher to carry over.
This isn't true. I can't remember if I posted it or not, but I took a look at the percentage of players at each position that finished in the top ranks of their position over the past five years. In most cases, IDPs exhibited at least the same year-to-year consistency as the offensive players.I'll try to find that data sometime this weekend.
Jene, I'd like to see that, in my findings, what people consider Studs today in IDP, are more often than offensive players, not studs tomorrow. Please post that. I guess it is open to debate on what you and I define as a stud, but with that said, if the data proves I'm wrong, I have no problem admitting it.I always try to avoid situations like 3-4 in the Parcells type defenses, try to get the WLB in Tampa2, etc. rather than focusing on the player itself. Too many things change on a year to year basis, in my personal opinion schemes rule at the end of the day.
I don't disagree with the scheme issue whatsoever, as you know. Just the belief defensive players don't necessarily hold value as long as offensive players.Hmmmm.....I found this in my offseason files, but I can't find it by Forum search. Maybe I wrote it and never posted it. Anyway, this may be a Honda

, but here it is. It does show that fantasy starters are more consistent from year-to-year on offense than defense, though how significant the differences are might be up for debate -- except at DB.__________________________The second installment in the Fun With Defensive Statistics series, which suggested that the year 2007 was a major aberration in defensive back production, prompted this third thread. A post in that thread by Toads raises an interesting question.Why does the generally accepted roster management of defensive backs (slough them during the draft, don’t overpay in trades, attack the waiver wire to find the hot hand) fly in the face of the supply-demand method of rostering nearly every other fake football position?Should we be targeting the rarest of animals – the consistent top performing DB – and prioritizing those players in our roster planning? Or should we continue to focus on lower tier RBs, WRs and LBs as so often happens? Is the slough DBs a valid default draft strategy at all?Consider the following charts:
Code:
Percentage of Players (Top 36 LB/DB, 24 DL) Who Repeat Their Performance the Following Year 2006-07 2005-06 2004-05 2003-04 2002-03 5YR AVGDL 38% 50% 42% 63% 50% 48.60%LB 50% 47% 50% 53% 36% 47.20%DB 28% 33% 33% 31% 36% 32.20%
A couple of quick notes. I chose to use the Zealots lineup (2 DL/3 LB/3 DB) as the benchmark for the worst starter cutoffs. Also, I used total year end points rather than points per game. That likely depressed the percentages across the board, but only slightly.A reasonable person might conclude the following.1. The many anecdotal claims that 2007 was a goofy year for IDPs, particularly at the DL and DB positions, now have some statistical support. The most recent thread was full of tables that showed just how depressing DB production in 2007 was when compared to a five year sample. This table shows that this year’s rankings (both DL and DB) showed less consistency on a year-to-year basis than any in the five year data sample. And fairly significantly so – the marks for this year were both outside a full standard deviation – for such a small sample size. 2. Over the five year data set, defensive backs are far and away the least consistent position on a year-to-year basis. That’s not surprising – the argument to slough DBs in favor of picking up the flavor of the week is a valid one. Some of that is probably due to lumping safeties and cornerbacks together. I’d guess that those leagues that break out corners and safeties into separate positions would see much better consistency percentages than the 32% five year DB average in the above table.3. It is a little surprising to see that the DL five year average is better than the LB average, especially since we’re sampling 24 players rather than 36. There is more variability in that data set than the other two positions, though, and the end result may change as our sample size increases. Also, the fact that so many “DL” are consistently poor producers (3-4 DL, many DT) may give the consistency score a small boost. Also, the 36% score between 2002 and 2003 drags the LB average below 50%.For many dynasty leaguers, the rubber meets the road over a three year window.
Code:
Percentage of Players (Top 36 LB/DB, 24 DL) Who Repeat Their Performance Over the Following Two Years (Three Seasons Total) 2005-07 2004-06 2003-05 AVG 3YR CUMUL PCTDL 29% 17% 25% 23.67%LB 22% 25% 28% 25.00%DB 17% 11% 6% 11.33%
The three year consistency percentages don’t look any better for the defensive back group. Make of those tables what you will for your own roster management strategies. For me, I agree with the original comment made by Toads. Supply-demand should be more of a factor than it is. If you think you’ve identified a player with the talent to remain an elite player against the above odds, I believe he should be a target for you. In the end, you still have to grab the 10 week wonder off the waiver wire instead of the 2 week wonder. I still think the odds are better gambling against injury and the fake football gods that you’ll grab a stud DB than the right waiver wire DB.Also, FWIW, here are the consistency percentages for the offensive positions and team defense/special teams.
Code:
Percentage of Players (Top 12 QB, 24 RB, 36 WR, 12 TE/TDST) Who Repeat Their Performance the Following Year 2006-07 2005-06 2004-05 2003-04 2002-03 5YR AVGQB 58% 42% 50% 58% 75% 56.60%RB 58% 50% 63% 54% 63% 57.60%WR 53% 56% 58% 50% 50% 53.40%TE 58% 75% 50% 42% 58% 56.60%TDST 58% 25% 50% 33% 58% 44.80%
Note that the team defenses are not more predictable than the majority of individual defensive positions, and, over the long haul, the least predictable of any fake football position. The offensive positions do in fact have higher consistency percentages across the board. However, I’d argue that it’s not as significant as it first appears – the player pool of “NFL starters” is much deeper on the IDP side and contributes to much of the statistical discrepancy.
