The Packers receiving corps definitely has more talent than the unit that played on Sunday but even if they were healthy and Funchess hadn't opted out would have been below average compared to the rest of the league.
I know you don't consider PFF a credible source (I wasn't able to find another one quickly though) but here's a list to their rankings of wide receiver groups entering the season with the Packers ranking 24th.

I agree there are worse units in the league but I wonder if the Packers one is good enough to win a Super Bowl.
We'll talk about it once that happens but I don't consider the chances for it to be decent.
Yeah, I get it. They aren't as talented at the position as they could be. Depending on what one believes about the draft, they either missed out on adding a talent, or didn't want to all that badly.
My point is that while I understand people's frustrations that they didn't take a WR in the draft, it's invalid to criticize the FO for the current group on the field, as no team could have anticipated losing Funchess to COVID, and then having Adams, Lazard, and St. Brown hurt at the same time. You take WR's number 1, 2, 3, and 5 away from any roster in the league, and what's left would be paltry.
I do consider PFF to be a credible source as far as football opinions go; I just don't consider them to be the final word. Looking through their rankings there, I see a few teams that I would certainly rate below the Packers group-- such as the Chargers, the Browns, the Giants, the Bears, and the Colts.
I think the Packers set themselves up this season to be somewhere in the middle of the league in terms of WR talent, but that many fans carry the perception that they're one of the worst in the NFL largely because of all the hubbub around not taking a receiving in the draft.
Beyond any doubt, the Packers could win a SB with this group at WR. Look back at the WR corps of recent Super Bowl champs and you'll see plenty of groups comparable to the current Green Bay squad, or worse.
What's more, they currently have the best offense in the league, and they haven't been close to full strength at the position. I realize that they will play tougher defenses, but they will also get guys back. And even if tougher defenses means they go from the #1 offense in the league to, like, 5th... you can still win a Super Bowl with that.
When a team plays lesser defenses, you don't discount the results, but rather you have higher expectations. The Packers have blitzed all of them, and are averaging 38 points per game. I'd say that should qualify to meet raised expectations.
