All anyone needs to do is look into the eyes and facial expressions of Mike McCarthy to see that he knows he's in trouble. For anyone in his position to see that his troops aren't responding to his attempts to cut down on his players' mistakes, it's quite obvious that he's feeling stressed and likely, freaking desperate. He knows Jerry is watching his every move and perhaps thinking in terms of sending him packing, in favor of hiring another HC.
I definitely wouldn't want to be in Mike McCarthy's shoes -- especially after Jerry openly made comments, in the past, to the effect of McCarthy being somewhat of a temporary fixture as his HC. The fact that he even mentioned Sean Payton and Dan Quinn as his possible replacements, likely didn't help MM's level of confidence, in terms of his sense of belonging. I can hardly imagine the temerity of any owner treating his HC in such a cold manner.
