Should I start CJ?

I know the Steelers D is solid, and our o-line is far from it, but the Jag's game has me excited. I want to start Stroud over Josh Allen in one league and Lamar Jackson in another. Gotta rep my boys, but I also don't want to set myself up for catastrophe if we get obliterated. How much better is the Steelers Defensive line than our backup o-line?
