The new shark move or just reactionary stupidity?
The Zero RB theory is the brainchild of
Shawn Siegele, who suggests
steering clear of running backs until the fifth or sixth round of a draft.
Zero RB is basically what it sounds like. You simply don’t draft running backs in the high leverage rounds. Depending on how a draft is progressing, I will draft either one high upside running back in Round 4 or 5, or I will draft none at all. My preferred lineup after five rounds is to own one tight end (Graham/Gronk) and four wide receivers. I then focus on selecting potential breakout players, the receiving back in timeshares, and backups in good offenses.

Zero RB has been gaining a lot of attention, but it
sounds like shots are about to be fired:
About halfway through my/our "Zero RB Is Dumb And You Should Feel Dumb" article. Get ready for math, behavioral economics and strong words..
-@Numberfire
I don't think Numberfire's rebuttal has posted yet, so I'll offer my own in the meantime. I read the original article when Sean wrote it. It was very well-written and entertaining, though as has been pointed out, it was hardly his "brainchild" (note: Sean never claimed it was, that came from the author of the Washington Post article who was obviously unaware of previous writing on the strategy by Waldman and many, many others.)
As much as I enjoyed it, here's a brief point-by-point rebuttal:
Claim 1: VBD doesn't work
- This one is pretty laughable. As Siegele admits, it's the dominant strategy used by expert drafters, and has been for over a decade. If it didn't work don't you think... umm... someone would have noticed by now?
Claim 2: Most people generate poor VBD baselines
- This goes hand-in-hand with claim 1, but completely undermines it. The problem isn't that VBD doesn't work, it's that people are doing it wrong. If I did
Prancercise for 20 hours a week and then complained that I wasn't getting ripped, you wouldn't say "exercise doesn't work", you'd say "you exercise wrong".
Claim 3: VBD lineups are "overwhelmingly fragile in the face of prediction errors"
- I can complain about projections like the best of them (I don't use them, personally), but all drafting methods are fragile in the face of bad predictions. VBD introduces two possible points of error (in the player projection and in the baseline projection), but it's a necessary evil because without the baseline projection there's no rigorous way to compare positions. Saying you shouldn't project baselines because it introduces more fragility is like saying you shouldn't predict player performance because it introduces more fragility. It's notable that all of the top experts in FantasyPros' expert accuracy rankings use specific projections. It's certainly not the only way to go, but it's clearly got a pretty good track record.
Claim 4: VBD lineups tend to be fairly balanced
This is just a flat-out misunderstanding of VBD. I've had drafts where pure VBD was telling me that I should be drafting an RB in each of the first 8 rounds, and I had to actually overrule that VBD suggestion and go off script. VBD is agnostic to your lineup so far; if VBD drafters tend to have a balanced roster, it's either because that's where the value was, or else it's because they
ignored VBD.
Claim 5: It makes sense to ignore RBs because they get hurt at a substantially higher rate than other positions
This data may be 13 years old, but until I see something more recent to the contrary, I'll assume it still holds. Drinen found that the average RB played about 13 games a year, the average WR played about 14 games a year, and the average QB played about 12.5 games a year, (that QB number definitely seems like it's been increased due to rule changes, though I haven't run any numbers on it.) Now, RB has an advantage in that workload tends to be transferred a bit more cleanly in the face of injuries (it's rare to see one WR take a huge majority of another WR's targets when that WR gets injured), so you can't just go and grab backup WRs when a starting WR goes down (although: Harry Douglas). The mechanics are different, but the injury rates are largely the same.
To be fair, again, I think the article was entertaining and well-written, and I think the strategy is totally valid (even if I disagree with his reasons for using it). Last year was clearly a season where "Zero RB" probably would have been the way to go, because there was so much chaos at the top of the RB rankings. Of course, the article was written in November after that was already obvious. Had all the RBs stayed healthy and productive, I wonder if we might have gotten a call-out to the article he'd written earlier about drafting RB-RB-RB, instead. It's a lot easier to identify the proper strategy with the full benefit of hindsight. I'm not picking on Sean or accusing him of some nefarious intent- I think the guy's awesome, I read most everything he writes, and his fantasy football success pretty much speaks for itself. I think he has every reason in the world to be confident. I just think his writing tends to overstate that confidence. It tends to be too black-and-white when the reality of fantasy football is expressed more in shades of gray.
One thing I do think he got exactly right is the perils of going with a balanced lineup in the draft (though, again, this is not a flaw with VBD drafting). People underestimate bust rates and assume the guys they pick in the first 7 rounds are "starters" and the guys after that are "backups", when in reality they should be assuming that half of their picks are going to bust, (meaning you're still drafting "starters" deep into the teens).
