How to watch a defenseman

Watch the gap, the passing lane, the net-front box-out and the first pass. Then check discipline.

In plain English

How it works

Gap at the blue line

Watch the space between the defender and the puck carrier at the blue line. Look for the defender standing the attacker up as the play arrives.

Stick in the passing lane

Look away from the puck for a moment. Is the defender's stick in the path between the carrier and the intended receiver?

Box out at the net front

Watch the defender's position relative to the attacker and the net. Look for the box-out that keeps the attacker from taking the space at the goal.

First pass out of the zone

Follow the defender after the puck is recovered. Watch the first pass out of the zone, not just the recovery itself.

Add discipline

Keep minors taken and minors drawn in the picture. Discipline belongs alongside the work at the line, in the lane and around the net.

D = defender · × = attacker · dashed line = puck path. Schematics show where to look.

The math, when you want it

The formula

The formula

This is a viewing checklist, not a scored formula: gap + passing lane + net-front box-out + first pass, with minors taken versus drawn alongside. No numerical weights are assigned to these observations.

Evidence and its limits

How we tested it

This is a viewing checklist, not a model, so there is no test score. These are the things to look for while you watch.

Keep this in mind

What it can't tell you

A few watched plays cannot establish a complete player ranking. This checklist gives you specific actions to follow; it does not assign a goals-added value to each one.
