Is Justin Herbert a buy in SF right now?

His fantasy numbers are way down so far this season due to lower volume and a run heavy offense but the talent is obviously still there.

What does everything think? Will he ever come close to his 2020/2021 numbers with Greg Roman as the OC? Or will his upside continue to be limited in the run heavy offense?

If you think he’s a buy, what’s the most you would be willing to give up for him in a trade?
