Two different coaching staffs see Lynch as not ready, which was his label when he was drafted. Goff went 0-7 last year so he was apparently not ready either. As you point out, he shows real potential this year. Goff benefited from being thrown into the fire -- not all guys do.
I think we have seen Semian's ceiling and Oz's too for that matter. I gathered that 300Paul's suggestion was that it might be time for us to bite that same bullet that the Ram's did last year.
