I know many want MM's job, But the team's worst problems are on the offense. KM is OC and is closest to those problems. Why would the OC not do something about this horrible penalty problem? Think of how many drives were killed by penalties! Not only is Moore's play calling really questionable, but the OC is obviously doing very little to curb that penalty problem.
If KM told MM "hey, we need to clamp down on this stupid penalty problem now", there's no way MM would disagree. But KM doesn't have what it takes to clamp down on anything. He's too soft. But he's Jerry's guy, and MM got stuck with him. Jerry's going to stand up for KM and MM knows it.
KM's offense was disorganized, and reeked for lack of discipline, and because of Jerry's thing for KM, MM is stuck between a rock and a hard place.
Am I being too lenient on MM? Maybe, but DON'T underestimate KM's share of the blame.
