Samples was out for sure, he is lucky he wasn't a midseason firing.. Brown back to RB makes sense, but I think I would fire him as well as the other coaches whose rooms underperformed like Shula.
Might be a lot of changes to the staff even if McVay sticks around, as the message can get lost over time due to familiarity. Plus this is a level that demands accountability and McVay needs to find a good run game coordinator. So we could see QB and WR room changes, maybe even OL.
Defensively changes at DB and DC are warranted. McVay prefers secondary knowledge with his DCs, but Henderson definitely deserves a look at DC.
Big changes ahead IMO.
