It was arguably most troubling part of the Jets' ugly 15-10 loss to the Bucs on Sunday.

Their offensive line couldn't block anyone.

Not in the run game, where the Jets averaged 2.9 yards per carry. Not in pass protection, where the Bucs hit quarterback Josh McCown 13 times and sacked him six.

And on Monday, coach Todd Bowles was left looking for answers.

"We had a bust here and there," he said. "We missed a few blocks. We didn't play well as a group. We didn't play well."

If the Jets want any success the rest of this season ... they'll have to find a fix.

The Jets, at 4-6, have played much better than expected this year. That, to an extent, has hidden some of their deficiencies. Because the Jets aren't a winless mess, it's easy to think they're playing better than they actually are.

The performance of the guys up front is a prime example.

The Jets are averaging just 101.6 rushing yards per game -- 20th in NFL. They're averaging 4.0 yards per carry -- 18th in the NFL. They've run for less than 60 yards in four of 10 games.

That's not good, but where New York really struggles is in pass protection

The Jets rank 23rd, per ProFootballFocus, in pass blocking efficiency. They've allowed 62 quarterback hits (6th most) and 32 sacks (second most).

Sunday's horrid outing against the Bucs wasn't an irregularity. It's the norm.

"It's not just them. It's everybody," Bowles said. "That's why we're 4-6. It's been inconsistent up and down. We have to play better with more consistency."

The Jets better hope there's a quick fix. If not, they're in trouble. Especially with what's coming up. After the Jets come off their bye this week, they'll face one elite pass rusher after another the rest of the way.

Up first will be the Panthers and ageless wonder Julius Peppers (7.5 sacks). Then it's the Chiefs and Justin Houston (7.5 sacks), followed by the Broncos and Von Miller (8 sacks). The Jets will play the Saints and Cameron Jordan (7 sacks) in New Orleans, and host the Chargers and Joey Bosa (9.5 sacks).

The only team the Jets play without an elite pass rusher? The division-leading Patriots (7-2) in Week 17.

McCown, and his 38-year-old body, has held up to this point. But the constant pounding will eventually take its toll.

If the Jets line doesn't step up, it will happen sooner, rather than later.
