Wide-9 vs Traditional 4-3: How Hafley’s Scheme Changes the Dolphins Defense

By Dolfan Radio Staff • July 2026

One of the most exciting tactical changes in Jeff Hafley’s defense is the heavy use of **Wide-9 alignments**. Here’s how it differs from a traditional 4-3 and why it matters for the Dolphins.

Why Hafley Likes Wide-9

The wider alignment creates natural pressure on the quarterback and forces offenses to adjust. It also allows the Dolphins to stay multiple — mixing 4-3 and 3-4 looks from the same personnel without heavy subbing.

This should be a big boost for Chop Robinson and the edge group this season.
