The bad news is the Steelers’ offense has been so bad fans have taken to chanting “Fire Canada” at Penguins games.

The good news is embattled, beleaguered and generally despised offensive coordinator Matt Canada and his troops have a golden opportunity to begin anew coming out of the Steelers’ bye this Sunday in Los Angeles.

The offense figures to be healthy for the first time since the regular-season opener back on Sept. 10 against San Francisco. Wide receiver Diontae Johnson is expected to be back. So is tight end Pat Freiermuth. And left tackle Dan Moore Jr. and right guard James Daniels.

They’ve had the bye to self-assess and to look ahead.

They should be rested, refreshed, re-booted and rejuvenated.

For this team at this time, Sunday constitutes that rarest of opportunities in the NFL, a do-over.

Except running back Najee Harris doesn’t want one.

“I wouldn’t say a do-over,” Harris maintained. “I wouldn’t want a do-over. I think that even our mistakes that we’ve had, it’s all good, it’s all learning. When we say a refresh, I don’t say a refresh as in we want to start the season over.

“It’s a refresh as in, we learned our mistakes, we got it. Every game’s not going to be perfect but we need to build off that and start the second half of the season.

“I wouldn’t take back anything.”

Fair enough.

What doesn’t kill you makes you stronger.

But with a season seemingly on life support even at 3-2, it’s time for the Steelers’ offense to at long last be heard from.

The goal back when this madness began was for the Steelers to be able to slug it out or shoot it out on a week-to-week basis, depending on the nature of what would be required based on the capabilities of their opponent.

Slug it out with the Ravens.

Shoot it out with the Bengals.

Repeat as necessary.

The defense hasn’t held up its end of that bargain as well as it’s needed to, either.

But the offense has for the most part shot itself in the foot.

The exceptions, such as the splash manufactured when necessary against Cleveland and Las Vegas, and the last-minute, game-winning drive quarterback Kenny Pickett and the offense somehow cobbled together against Baltimore, haven’t been enough to assuage Steeler Nation’s growing rage.

Hence the chant during the Penguins’ opener, and the T-shirts and bumper stickers and homemade signs that are showing up seemingly everywhere.

The climate is such that the Steelers need not be surprised in the event they land in LA to find the iconic “Hollywood” sign has been vandalized to read “Fire Canada” instead.

How has that not happened on Mount Washington already?

A tide of negativity that’s threatening to reach Tsunami-like proportions, amazingly, can yet be turned against the Rams, who boast an All-Word, All-Time Great on defense in Aaron Donald and not much else to worry about.

But given the potential combustibility of Rams quarterback Matthew Stafford and his elite wide receivers, and the aforementioned issues the Steelers’ defense has been dealing with, Sunday may well be put up or shut up time for an offense that too often has remained silent.

If it’s not a do-over they’re seeking, the Steelers’ offense must at least endeavor to do better.

Much better.

If not now, when?
