# Handcuff

## Short Definition

The backup running back rostered as injury insurance for your starter—if the starter goes down, the handcuff inherits elite workload on a run-first team.

## Definition

A handcuff is the backup running back on a team whose starter is a significant fantasy asset—rostered specifically to protect against the starter's injury. If the starter goes down, the handcuff immediately inherits a large workload on a team built around that runner, potentially becoming a RB1 or RB2 value overnight. The name comes from the idea of binding yourself to your starter's fate.

Handcuffing is most valuable when the starter is injury-prone, when the team has a strong offensive line and run-game identity, or when the backup's ADP makes him a cheap insurance option late in drafts. A starter worth a third-round pick combined with a handcuff available in the 12th round represents relatively low-cost protection on a high-value asset.

The decision whether to handcuff depends on roster construction and league size. In deeper leagues, handcuffs have higher absolute value because they are harder to acquire on waivers when needed—other managers may have already scouted the backup. In shallower leagues, the handcuff may be available on waivers if the starter gets hurt, making roster investment less necessary.

Handcuffing has an opportunity cost: each roster spot occupied by a handcuff is a spot unavailable for a different contributing player. Managers who handcuff every running back dilute their overall roster quality. The handcuff decision is a risk management calculation—how much of the starter's injury risk justifies spending a late-round pick on insurance versus investing that pick in another contributor.

## Example

"You've got their starting back in the third round—grab the handcuff in the 11th. If he stays healthy you wasted a late pick. If he gets hurt, you just turned a potential disaster into a seamless transition."

## Common Confusion

Handcuffing is a running back strategy—it rarely applies to other positions in the same way. Backup quarterbacks and receivers rarely inherit their starter's full role the way a running back handcuff can. The concept works specifically because starting running backs absorb such a high percentage of their team's backfield touches that the backup inherits elite opportunity on injury, which doesn't replicate at most other positions.
