Yeah OG would be lucky to ever be as good on offense as Jaylen is now. You see little hints of what Jaylen could do on offense if he acquires a bit of consistency. OG has no offense whatsoever and will have to be taught these things from scratch.
He's more of a physical specimen so he has a bit more upside if we see some sort of miraculous improvement, but that alone doesn't mean he's a better prospect.
