I axually did this analysis a couple of drafts (and days) ago, but I didn't have time to write up the results until now. I think it can still be instructive.
At the time of the analysis, I had drafted 19 fantasy football teams so far this preseason. 9 of them were 24-player rosters (the RTSports BBCs), 3 of them were 20-player rosters (RTSports auction Draft Masters), 3 of them were 18 player rosters (Yahoo Multiflex+Superflex managed auction leagues), and 4 of them were 16 player rosters (3 RTSports High Stakes managed auction leagues and 1 Colton & the Wolfman 14-team Best Ball snake draft). And of course all of them are money leagues, from $20 to $250.
To those 19 teams, I have drafted almost 400 players (391), an average of 20.6 players per roster. I have drafted 80 different unique players to those 391 roster slots, but the 30 players that I have on 5 or more teams account for almost 300 (293) of those 400 (391) players (74.9%). This means that for every one of my 20-player rosters, 15 of those 20 players appear on at least 4 more of my teams. For every one of my 24-player BBCs, 18 of those 24 players appear on at least 4 more of my teams.
That's a pretty highly focused and undiversified portfolio, which is of course the best investment strategy--when you are right. (And I'm Axe Elf, so...) I'm pretty amazed that I have been able to consistently snag so many of my targets so many times in the ten snake drafts I've done--although they're getting harder and harder to get at the ADPs that made them such values six weeks ago.
I axually kind of think that the wave has crested in terms of the pros and cons of early drafting--the upside being that you can get some amazing draft values earlier in the summer, but the downside being that you have to make it through the injury minefield of training camp and preseason. And that's kind of where we are right now, 6 weeks before opening Sunday--the draft values are starting to normalize, but injury season is just starting. My highly undiversified portfolio is less vulnerable to injuries in that I am depending on fewer studs to stay healthy, but also more vulnerable to the extent that an injury to one or two of my key players could essentially end my season.
By position, I have drafted 52 QBs. That's 2.7 per team, and 13.3% of all my drafted players. 40 (76.9%) of my QBs are Daniel Jones (on 17 of 19 teams), Patrick Mahomes (on 16 teams) or Ryan Fitzpatrick (7). QBs I wish I had more of: Matt Ryan (on 4 teams) and Kirk Cousins (2). Both are fairly cheap, but they are the QB11 and QB12, respectively, from last year. I also managed to get only one share of Aaron Rodgers during the holdout scare a couple of months ago. Worst QB picks: Cam Newton (2), Jameis Winston (2) and Jared Goff (1). I mean, they're all like 3rd QBs on my teams, but they're my QBs with the biggest questions.
(I've added 2 Jones, 2 Ryans and 1 Cousins in 2 drafts since this analysis was completed.)
I have drafted 102 RBs; 5.4 per team, and 26.1% of all my drafted players. 76 (74.5%) of my RBs are Chris Carson (14), Raheem Mostert (13), Mike Davis (11), Joe Mixon (10), Trey Sermon (8), Nyheim Hines (7), Tarik Cohen (7) or Latavius Murray (6). I got a lot of that Mostert/Sermon combo early on in the best ball leagues (and they should be fire in that format), but it's getting a lot harder to execute that RB double-draft these days. RBs I wish I had more of: Derrick Henry (3), Ezekiel Elliott (1), Aaron Jones (2), Damien Harris (1), Travis Etienne (1) and Darrell Henderson (1). Henry and Zeke have the best chances of being the #1 fantasy performer this year, but they are hard to get in both snake and auction formats. I've had my eye on Etienne through his career at Clemson, and his upside is literally sky high. He could be the next CMC, if he's given the same kind of touch volume. Worst picks: J.D. McKissic (1), James White (3) and Marlon Mack (1).
(I have added 1 Jones, 1 Zeke, 1 Carson, 1 D.Harris, 1 Cohen and 2 Davis since this analysis was completed.)
I have drafted 125 WRs; 6.6 per team, and 32.0% of all my drafted players. 91 (72.8%) of them are Kenny Golladay (14), Brandon Aiyuk (13), CeeDee Lamb (12), Amon-Ra St. Brown (11), Robert Woods (10), Mike Williams (10), Adam Thielen (8), Will Fuller (8) or Brandin Cooks (5). Lamb, Woods, Golladay and Thielen all have top 10 potential, with Aiyuk, Williams and Cooks all potential top 20 candidates as well. WRs I wish I had more of: Robby Anderson (4), Tyreek Hill (3), Tre'Quan Smith (3). More Mahomes/Hill stacks would be nice. Worst picks: DeVante Parker (1), Cole Beasley (1) and A.J. Green (1).
(I have added 1 Thielen, 1 Aiyuk, 1 Anderson, 2 Woods, 2 Lamb, 2 Golladay, 2 Cooks, 2 Williams, and 2 Amon-Ra St. Brown since this analysis was completed.)
I have drafted 55 TEs; 2.9 per team, and 14.1% of all my drafted players). 49 (89.1%) of them are C.J. Uzomah (15), Evan Engram (8), Jared Cook (8), Robert Tonyan (6), Anthony Firkser (6) or Dalton Schultz (6). TE I wish I had more of: Tyler Higbee (3). He seems like a 100-target lock. Worst picks: Dalton Schultz (6) and Hayden Hurst (2).
(I have added 1 Higbee, 1 Engram, 1 Firkser and 1 Uzomah since this analysis was completed.)
I have drafted 29 Ks; 1.5 per team, and 7.4% of all my drafted players). 20 (69.0%) of them are the Arizona Cardinals (11) or Minnesota Vikings (9). They're both dome kickers for effective offenses. K I wish I had more of: Atlanta Falcons (4). Another dome kicker for an effective offense. Worst picks: Denver Broncos K (1) and Green Bay Packers K (1).
(I have added 1 Cardinals and 1 Vikings since this analysis was completed.)
I have drafted 28 Ds; 1.5 per team, and 7.2% of all my drafted players). 17 (60.7%) of them are the Minnesota Vikings (9) or the Kansas City Chiefs (8). Ds I wish I had more of: Los Angeles Rams (2), Washington Football Team (2), New England Patriots (2). Worst picks: Chicago Bears D/ST (3) and Tennessee Titans D/ST (1).
(I have added 1 Patriots and 1 Vikings since this analysis was completed.)
So overall, about 1/3 of the players I have drafted have been WRs, 1/4 of all the players I have drafted have been RBs, with equal shares of 1/7 QBs, 1/7 TEs, and 1/7 Ks & Ds (51% Ks and 49% Ds).
I wonder what the numbers will look like after 6 more weeks of drafting (and injuries).
