I don't even know where to begin.
how about you start by ranking McCarthy's attributes as a head coach (and note how each compares to league average)? we are so many light years apart when it comes to this clown that this is likely to be pointless but at the very minimum it will be mildly entertaining to see casual fan's perspective
off the top of my head, here are some attributes to be ranked:
-in-game management (clock management, challenge usage, etc.)
-offensive gameplanning and strategy (this is often the OC's responsibility but because Cheddar is an 'offensive' coach we list this as well)
-talent development
-performance maximization (motivation, speeches, WIM, etc.)
there must be a few others because he patently blows **** at those listed above and you seem to think he's in the upper quartile so I would love to hear them. NOTE: "going 15-1", "winning a superbowl", and "likes Cheddar Chilli" are NOT attributes. please do not bring them up.
I seriously don't see anything he does that is even slightly competent (save for some well drawn up offensive plays and maybe crediting him for some of Rodger's stellar development). The worst part is, his terribleness extends even beyond being bad at those listed attributes. for example, there's not many coaches who would have that clout to tell Rodgers to stop running around and putting himself at risk (the actual hit he took is not a great example, but there are millions of them), but it's a damn fact that Mike McCarthy is not one of them. That's a problem.
this has been a year of evolution in the NFL and we are beginning to see coaches that are willing to flexibly use their brains (Trestman, Chud, Chip Kelly). I can't blame Mccarthy for this lack of flexibility because it's likely he's just plain dumb, but that doesn't change the fact that he shouldn't be the head coach.
