If Burrow is out Zac will be exposed

It's known that Taylor/Callahan aren't of the caliber of McVay, Shanahan, or McDaniel.
It's heavily dependent on good QB play.

Bengals also have a bad blocking/offensive scheme that isn't going to magically be able to be turned into a Top 10 rushing attack now that Burrow is out.
Bengals will have a middle-of-the-pack rush attack at best, bottom-tier occasionally.
The passing game will decline, there's no way around it.

It will ultimately be up to the defense (specifically run defense) to get back to their form of previous years if this team is going to stay in and win games the rest of this season.

....Or maybe Browning is that secret sauce we just had no idea about, and he'll light the league on fire!
