As the current 1.06 in rookie drafts and RB8 in dynasty overall (according to KeepTradeCut), the 199-pound Jahmyr Gibbs is a fairly unique proposition as an undersized running back who the dynasty community expects to be a high-end fantasy asset. I think it’s reasonable to ponder whether that uniqueness is a good or bad thing.
In recent years, the approximate threshold for RB2-level production in PPR is 12 points per game, and since the turn of the century, there have been 28 running backs to eclipse such a threshold at lighter than 205 pounds (according to Pro Football Reference):
- Jahvid Best
- Ahmad Bradshaw
- Jamaal Charles
- Tarik Cohen
- Warrick Dunn
- Austin Ekeler
- Andre Ellington
- Kevin Faulk
- Justin Forsett
- Charlie Garner
- Myles Gaskin
- Ronnie Hillman
- Nyheim Hines
- Chris Johnson
- Dion Lewis
- Phillip Lindsay
- Elijah Mitchell
- Bilal Powell
- Ray Rice
- Theo Riddick
- Devin Singletary
- Steve Slaton
- CJ Spiller
- Darren Sproles
- Chris Thompson
- Brian Westbrook
- Cadillac Williams
- Danny Woodhead
Those 28 backs combined for a total of 65 RB2-or-better-level seasons in the post-2000 era, meaning we get an average of 2.8 sub-205-pound runners to produce like fantasy starters in a given year. The rarity of players in this archetype is evident, but even within it, I would argue that Gibbs doesn’t really look much like any of his successful predecessors (let alone like the 214-pound Alvin Kamara, the 212-pound D’Andre Swift, or the 208-pound Aaron Jones that he often gets compared to).
