Khyiris Tonga is gone, and the Patriots' defensive line suddenly looks thinner than expected heading into a crucial offseason. But here's the thing: Mike Vrabel's conviction that this group can still get the job done isn't baseless bluster. It's calculated optimism built on some actual depth pieces.

The departure of Tonga removes a body from an already crowded interior, but the Patriots still have Christian Barmore anchoring the middle—a legitimately talented player when healthy. Cory Durden proved serviceable last season and remains a capable rotational option. The real question isn't whether they have warm bodies; it's whether they have the right ones to execute Vrabel's scheme, which tends to be aggressive and reliant on penetrating defensive tackles who can collapse the pocket from the inside.

What matters now is execution. The Patriots have names like Jeremiah Pharms Jr., Eric Gregory, Travis Shaw, and Leonard Taylor III competing for snaps. That's depth on paper. But paper doesn't generate QB pressure or stuff the run. The organization's confidence in this group will be tested immediately—there's no grace period when you're retooling after a Super Bowl loss to Seattle.

This isn't panic mode. Vrabel came in knowing he'd need to rebuild certain areas, and the defensive line rebuild is clearly a work in progress. The departure of Tonga is a setback, sure, but it's not a death sentence if the remaining players step up. Dre'Mont Jones and Milton Williams on the edge give them some upside in the pass rush game. The interior just needs to hold the line.

The confidence is real. Whether it's justified? That answer comes in September.
