For this mythbusters article, I tested the data on handcuffing your elite RB as insurance.
The toughest part was defining what population for the study. I didn't want classic timeshare situations to count as "handcuffs", more the elite RB who owns a large % of carries in the offense.
I started with 2016–2024 preseason RB1–RB12 ADP RBs. I used preseason ADP + opening rosters/depth charts to identify the guy fantasy managers would have actually considered the handcuff BEFORE the season started. I didn't want to look backward after an injury and just call whoever got the carries the “handcuff.”
That left 44 high-confidence RB1/handcuff pairs and 43 fantasy-relevant games where the RB1 was unavailable.
First thing I tested:
When the Handcuff was Needed, Were They Available?
The handcuff was also unavailable in 5 of those 43 cases (11.6%).
Some examples:
- Nick Chubb / Kareem Hunt, 2021 — Hunt was already on IR when Chubb missed Week 10
- Alvin Kamara / Tony Jones, 2021 — Jones was still on IR when Kamara missed Week 10
- Antonio Gibson / J.D. McKissic, 2021 — McKissic was on IR when Gibson was unavailable Week 17
So right off the bat, there's about a 1-in-9 historical failure rate where your “insurance” wasn't even available when you needed it.
If they were available, how'd they perform?
I compared the handcuff's share of RB carries to the starter's established share before the injury. I considered the role to have transferred if the handcuff came within 10 percentage points of the starter's normal RB carry share.
There were 37 cases we could classify.
25 of 37 (67.6%) inherited a comparable or LARGER rushing role.
And when that happened, the results were actually amazing (take note DFS players)
RB1 before injury → Handcuff after injury
RB carry share: 58.9% → 73.2%
Opportunities/game: 16.9 → 19.4
Total yards/game: 88.7 → 91.4
PPR/game: 14.9 → 16.7
The 73.2% surprised me the most. When teams actually handed the job to the backup, they tended to concentrate the backfield more around them, not less. Assuming this is a factor of a skill disparity between RB1-> RB2 being smaller than RB2 -> RB3. In these handcuff weeks, they just trusted the RB2 who had probably previously getting some work to take on not just the new role of RB1, but some of their old RB2 work.
Some individual examples:
Latavius Murray replacing Alvin Kamara, 2019 W7:
93.1% of RB carries, 33 opportunities, 32.0 PPR
Tony Pollard replacing Ezekiel Elliott, 2020 W15:
75.0% of RB carries, 21 opportunities, 31.2 PPR
Justin Jackson replacing Austin Ekeler, 2021 W16:
68.8% of RB carries, 20 opportunities, 34.2 PPR
Jamaal Williams replacing D'Andre Swift, 2022 W4:
82.6% of RB carries, 22 opportunities, 23.9 PPR
So that's a pretty strong argument for handcuffing.
Except...
The other 12 of 37 cases were not great.
When the handcuff was healthy but didn't inherit the role:
RB carry share: 73.8% → 26.4%
Opportunities/game: 19.5 → 8.4
Total yards/game: 91.8 → 35.1
PPR/game: 15.8 → 7.0
It wasn't usually “the backup gets 80% of the starter's role.”
The role basically disappeared.
2017 Darren McFadden might be the best example. Ezekiel Elliott finally got suspended, which was basically the exact reason people drafted McFadden. McFadden got one opportunity in Elliott's first missed game. Dallas gave the backfield to Alfred Morris instead.
What if I don't handcuff?
But I still didn't think that answered whether handcuffing was actually worth the draft pick, because there's an opportunity cost.
So I compared every handcuff against other RBs being drafted within ±12 RB spots of him that year.
Season-long results:
Handcuff: 110.1 avg PPR points
Comparable RB: 109.0
10+ PPR games: 4.41 vs 4.44
15+ PPR games: 2.20 vs 2.19
20+ PPR games: 1.02 vs 1.06
Basically identical. A difference of 1.1 fantasy points over an entire season.
That's why I don't think this myth is really CONFIRMED or BUSTED.
You're making two different bets.
Draft the handcuff and you're buying insurance on a backfield you've already invested heavily in. If the starter goes down and the role actually transfers, history says that payoff can be huge.
Draft another team's RB instead and you're diversifying. That player can become valuable without anything happening to your RB1.
Historically, neither strategy produced meaningfully more fantasy points, but I thought it was worth sharing the results anyways. Let me know what you think!
