In the Trey Sermon thread, some folks offered they’d probably take the cheaper option (Raheem Mostert) a few rounds later since their rankings/projections are pretty close. That led to a good discussion revolving around The Ambiguous Backfield study by JJ Zachariason (NumberFire, Late Round QB podcast.) Turns out the data points to a sort of wisdom of crowds result, that the higher ADP (player drafted first) is more likely to be a breakout league winner. You can check it out in the Sermon thread, read about it
here, or give it a
listen.
Yesterday my favorite FF YouTube channel had a discussion on a less extensive (but still interesting) study they did, specifically to see if it might give some clues on the Gordon/Williams backfield situation.
2nd Round RB Production, 2011-2020
29 players drafted in the 2nd round, 3 never got on the field bc if injury, so sample size = 26
looking at those 26 rookies & the incumbent RB on the roster:
- the veteran outproduced the 2nd round RB 8 times (30.8%)
- the rookie finished higher in FF 18 times (69.2%)
when the rookie received at least one touch in 10G
(19/26)
- 14 times (73.7%) the rookie finished higher
- 5 veterans finished higher (2011 Reggie Bush over Daniel Thomas, 2012 3rd stringer Knowshon Moreno over Ronnie Hillman after McGahee injury, 2014 Frank Gore over Carlos Hyde, 2016 DeMarcus Murray over Derrick Henry, 2020 Darryl Henderson over Cam Akers)
the next one is insightful for the folks who have said I’ll just draft both
- only twice have both RBs been useful, each finishing inside the top 30. Both times it involved Gio Bernard - with Jeremy Hill In 2014, with Joe Mixon
Top 20 when the rookie received touches in at least 10G:
- Veteran RB - 4 times (21.1%)
- Rookie RB - 8 times (42.1%)

I appreciate the post. Its intruiging.
At the same time I am skeptical of these narrow definitions and the selection bias that happens when people do this. The 2nd round is a pretty narrow sample.
I went into stathead and did a search of the criteria. Here are the RB who come up in the search:

While the results of that study may be accurate I think presenting the information as a percentage is somewhat misleading because in many cases the rookie may have scored the most fantasy points, but not by that much.
In the case of Swift Adrian Peterson still had more rushing attempts than Swift did his rookie year.
In Taylors case Marlon Mack got injured early. Not saying Taulor wouldnt have outperformed Mack anyways, and perhaps by a lot, but if you are going to exclude the rookies who got hurt, it seems to me the same treatment should be given to the incumbents.
Can Akers outscored Henderson by 20 points in standard scoring while Henderson outscored Akers in PPR by 29 points. Close enough that I would call this more of a tie.
I could keep going but perhaps you see where this is going.
As far as Williams vs Gordon perhaps one should narrow the criteria to how many times has a 2nd round rookie outperformed a veteran RB who was a 1st round pick? Because thats more what this situation is than just drawing from a ton of different teams and circumstances.
In the RB study I did I found that the rookie season is the least productive of a RBs first 6 seasons in the league on average and there are a lot of different reasons for that. One of the main ones being that the rookie often has to time share with other RBs already established on the roster. The mileage on this varies a ton because some of these RB have stronger competition than others.
A 2nd round pick is a pretty strong investment into a RB and teams usually are not doing that unless the RBs they have are not part of their long term plans. If they were the team would use that 2nd round pick on a different position most of the time.
In any case I would hate for people to read your post and come away from it thinking Williams has a 70% chance to outscore Gordon this season.
A better way to approach this might be to look at the teams draft history instead of looking at it league wide.
Since 2000 here are the RB Denver has selected in the first 4 rounds:
1 2018 3 71 Royce Freeman RB 22 2018 2020 0 0 0 9 46 8 Oregon College Stats
2 2016 4 136 Devontae Booker RB 24 2016 2020 0 0 0 15 77 7 Utah College Stats

4 2012 3 67 Ronnie Hillman RB 20 2012 2016 0 0 1 17 56 15 San Diego St. College Stats
5 2009 1 12 Knowshon Moreno RB 22 2009 2014 0 0 3 33 63 45 Georgia College Stats
6 2005 3 101 Maurice Clarett RB 0 0 0 Ohio St.
7 2004 2 41 Tatum Bell RB 23 2004 2008 0 0 1 22 54 22 Oklahoma St. College Stats
8 2003 4 108 Quentin Griffin RB 22 2003 2004 0 0 0 6 16 5 Oklahoma College Stats
9 2002 2 51 Clinton Portis RB 21 2002 2010 0 2 7 72 113 108 Miami (FL) College Sta
I see a lot of miss here.
Freeman Ball and Hillman ended up being outperformed by UDFA RB Lindsey and CJ Anderson.
