^ Putting aside that McC's playcalling became very predictable (where I and a number of others here could predict plays), McC was lacking in some of the most elemental aspects of being an OC.
One of the prime responsibilities of an OC is to come up with a game plan in how to attack the opposing team's D.
Common sense, alone, states that you attack their weak point.
But somehow, McC, in coming up with his game plan against Army (an Army program that was really struggling at the time) decided not to attack the secondary (a well known weakness), but instead, cane up with a game plan to run the ball against the Army D (using a big dose of Colter) and when the Cats did pass, it was dink and dunk.
After little success, thought the Cats would change things up in the 2nd Q, but nothing.
But was completely flabbergasted when they continued to do the same after halftime (though they would make the adjustment then).
So, during the course of 3 quarters, the Cats would go on to punt the ball 7 times; this isn't Michigan's D or even Iowa, but a bad Army D.
By the time they switched things up for the 4th Q, it was too little too late.
Now, it would be one thing if this was a one off mistake, but we kept seeing similar mind-numbing decisions time and time again.
Case in point the M00N game.
Siemian was getting lit up by the UM pass rush, so McC's "genius" adjustment was to have Trevor take the snap further back (to little avail).
For 3 quarters, thought Siemian must have a bum leg, as that had to be the rationale in not moving the pocket.
But much to my surprise, that's what they ended up doing in the 4th Q - which resulted in the furious comeback.
Or what about taking half a season of seeing the Cats hand off the ball deep in the backfield on 3rd/4th and short with predictable results before finally seeing the light and switching to the QB sneak.
But of course, once that switch led to much better results, McC couldn't resist a going to the well one too many times like in the Purdue game which led to Siemian's injury which effectively ended any chance of getting 6 wins and going to a bowl game.
Saw that the PU D was bringing the kitchen sink in stopping the QB sneak, so was yelling at the TV for McC to switch the call.
Can go on and on about other things like not realizing that his O-line was tipping off plays.
This is all pretty basic and rudimentary stuff - where someone like myself who "never had never strapped it on" knew what should have been done/what changes to make.
McC would eventually make those changes, but way too late.
Now, wouldn't place all the blame on McC, since Fitz probably had a hand in it.
