Why's that? Rivera is one of the best and is regarded by his peers with that respect. When the Panthers crumble it's usually because Cam is still as immature as a 4 year old or Luke is out of the came with a concussion.
McVay is a one season coach, judge it in 2 more years. It matters just as much as him having any though by your standards said above. If the league is about coaching, a guy who hasn't coached in a playoff game surely is rated below a guy who has won several or at least been in them.
Jags D right now is better than the Vikings. The problem with the vikings is that if Harrison Smith doesn't play lights out, you can go over the top on them easily.
