Because he's the HEAD coach..... not just the OC. As a HEAD coach he's been OK. As an OC he's failed and that's why he will probably not be around much longer. I am able to seperate the two. The last three years have had some good moments. I've certainly seen much worse as a Bears fan. I don't hate the guy at all. I actually kind of like him. But it is a results based business and the offense hasn't been fixed.... so like or not..... he'll probably have to go. But he certainly hasn't done enough for me to reach hatred levels.
Honestly I have a very simple way for an honest fan who's willing to be open-minded and not put their conclusion before the evidence to reevaluate Matt Nagy. Not arguing to put him in Canton by any stretch, but a simple exercise to reevaluate his scheme and the effectiveness of that scheme.
Re-watch as many games as you possibly can where Matt is the head coach and Mitch is the quarterback who plays the entire game.
And I want you to focus in on one thing on offense and only one thing.
When the ball is snapped, focus on how many open receivers you see from the time Mitch has the ball in his hands to the time he throws it.
Make note of the number of times where there is an open receiver and Mitch flat out doesn't see the open receiver. You can ignore his overthrows. We aren't talking about missing the receiver but just not even seeing that they are open.
You will find that the number averages to between 8 and 13 times a game. And I do believe there's one in there where it's as many as 18 times.
Now a dumb curmudgeon fan who wants to put his emotional hatred above everything else will just kick back and say "so what! Nagy bad!"
in more intelligent Bears fan will sit there and think on that for a second and realize "hold on. That means at least 8 to 13 times a game, the scheme worked and we had receivers open. We just didn't have a quarterback who could get them the ball..."
An even smarter fan might start looking at games from other teams who have at a bare minimum average level quarterbacks, like an Andy Dalton, and compare that exact measurement, disregarding everything else for a moment, and realize most average quarterbacks tend to at most not see the open receiver between 3-5 times a game.
And realize that is huge difference and a lot of yards left out on the field between an average NFL quarterback, and Mitch trubisky....
