In the midst of the Dallas Cowboys 4-game win streak has been the incredible play of the defense. Specifically the pass rush, highlighted by Micah Parsons, Randy Gregory and DeMarcus Lawrence.

For good reason too, they rank among the best defenses in terms of pressure, sacks and forced fumbles. Simply put, the front 7 has been unstoppable.

However, the unit that might make the biggest impact in the postseason is the secondary. Not simply because of Trevon Diggs and his league leading interceptions (11) and pass breakups (25), but the entire unit.

A secondary unit that’s getting healthier, and deeper.

We’ve seen all year just how good these players have been, and adding Kelvin Joseph to this list after his first career start is a positive sign. Even if he goes back to CB4, quality depth behind the starts is reassuring.

What’s even more reassuring is having a coach who knows defensive backs and how to use them.

Defensive coordinator Dan Quinn knows all too well how essential a great secondary can affect the playoffs, having coached in the Super Bowl 3 out of 4 seasons. Just ask the famed “Legion of Boom” who became one of the scariest units in the NFL over the last decade.

5 of the last Super Bowl winners finished top 10 in creating turnovers. Currently, the Dallas Cowboys defense leads the league with 33 turnovers with 2 games left.

Even better is that they’re likely to play one of the least accurate QBs in round 1 (Taysom Hill and Jalen Hurts). After that, they would play one of the league leaders in interceptions (Matt Stafford and Tom Brady) in round 2. All quarterbacks the Cowboys are all very familiar with.

It’s not an end-all be-all that the Cowboys will succeed in the playoffs, but history suggests the secondary will factor. The quality depth the defense has at both corner and safety is a positive sign for the chances for a championship.
