The Bills have a theoretical breakout candidate at running back in last year's second-rounder James Cook (pictured). They have a couple of capable veteran runners in Damien Harris and Latavius Murray, and another versatile guy in Nyheim Hines. But will they have a good fantasy back? That seems less likely.

For one thing, the team will probably favor a committee, with a main runner, a passing down specialist, and maybe an additional back who takes on a share of those opportunities. For another thing, Josh Allen will probably run in a healthy share of the touchdowns. Add up all the negatives, and it's not a recipe for fantasy success.

That's been the case throughout the Allen era. In the five years he's been in the league, Buffalo hasn't had a running back finish higher than 20th at the position (PPR) and only twice has it had one finisher higher than 30th. Looking at the top 100 running backs in fantasy leagues since 2018, the Bills have placed exactly one player in that group: 2021 Devin Singletary, who is the 89th-best PPR back since 2018.

Table shows every Buffalo running back to have a significant workload (200ish total yards) in a season over the past five years. Singletary, who's now in Houston, is the only guy with a top-150 (overall) performance in those seasons. (First ranking number is their performance at running back in that specific season, second overall since 2018.)

I think Harris, who scored 15 touchdowns two years ago, is a lot better than 33-year-old Murray; he should be the main runner. And the team would probably like Allen taking fewer hits, so maybe Harris scores a larger percentage of the rushing touchdowns than past Bills backs. Cook should be the main back in passing situations, so any positive talk about Hines can be largely dismissed. If there's a back on this roster who catches 60 balls, it should be Cook, giving him some appeal in PPR leagues.

But the Bills having a difference-maker at the position? That doesn't seem particularly likely. Cook or Harris will have to be available pretty late for me to take a chance on them. Cook will definitely be selected earlier than I'd take him. Harris has more of a shot to make it onto one of my teams as a late-round pick.
