I mean it is what it is at this point (a John Foxism there for you). Hopefully he stole McVay's playbook on the way out and he's being groomed for the long-term as a play caller under Reich.
I can't see the post you quoted, cos **** that schtick, but yeah it's a hire I predicted. Not so much Brown, but a young OC that's going to be happy not calling plays whilst Reich flexes his muscle.
