The now 4-2 Pittsburgh Steelers almost fell to 3-3 on the regular season, and the defense's early struggles against a Jalon Daniels-led Tampa Bay Buccaneers offense were a big reason why. Luckily, the Steelers' defense turned things around in a huge way during the second half, but Pro Football Focus' newly revealed Week 6 grades have given us a better idea of which players were responsible for the near-loss.

From two of the team's top edge rushers to a linebacker who's been heavily criticized this season, here's a look at the Steelers' worst PFF grades on defense.

Worst grades on defense

• 5. LB T.J. Watt — 57.1

• 4. LB Patrick Queen — 46.8

• 3. DE Gabriel Rubio — 43.1

• 2. LB Nick Herbig — 42.8

• 1. CB Brandin Echols — 35.4
