# #1 / #2 / #3

## Short Definition

Labels receivers from outside in—#1 is the widest, #2 is next inside, #3 innermost—used to assign coverage matchups and route responsibilities.

## Definition

The #1/#2/#3 system numbers eligible receivers from the outside in, on each side of the formation. The widest receiver is #1. The next receiver in—slot, detached tight end, or back out of the backfield—is #2. A third receiver to the same side is #3. The numbering resets independently on each side and is based on alignment, not player type.

The system gives defenses a shared language for declaring coverage responsibilities without naming specific players. A corner knows he has #1. A nickel knows he has #2. A linebacker knows if #3 releases into a route, he covers him. The numbers are how pattern-matching and man-coverage systems assign jobs based on where receivers line up rather than who they are.

## Example

"Trips right—#1 outside, #2 in the slot, #3 in the inside slot. The linebacker has #3 on any out route. Watch him—#3 releases to the flat, linebacker is right there before the throw. That's pattern-match coverage working off the numbering system."

## Common Confusion

People assume the numbers are fixed to specific players or positions—that #2 is always the slot, #1 is always the X receiver. The numbers are relative to pre-snap alignment, not identity. A motion can shift who is #1 and who is #2 before the ball is snapped.
