My perspective:
I thought CPJ was way ahead of most other coaches on game day. He had 4 down mentality. He understood how to win, to manage the clock, to call plays, to adjust his blocking, to maintain drives, to eat up the clock and shorten the game, and maybe most importantly how to score in the red zone. He had some short comings IMO like in the passing game and developing depth by not playing enough playersI On non game days there were some obvious shortcomings (such as recruiting, media interface, attention to special teams and D, and more).
I can readily support CGC's actions to transform the program (on all but game day). I even agree with most of it. What is frustrating is game day such as "rookie" mistakes such as clock management, penalties for back to back 12 men on the field, some undisciplined personal fouls, playing Yates one play, and QB management. On offense there is play calling in general (plenty of examples), inability to sustain drives (back to play calling), lack of plan for power running to gain short yardage, pathetic red zone performance, poor punt coverage, terrible KO return performance, and a TOTAL offensive transformation without a more "gradual approach" or taking advantage of existing opportunities or players (Oliver, Option running, screens to our playmakers). I hate the gun in short yardage and red zone, the dinky short yardage passes, the continual one yard runs up the middle on 2nd and long, and in key situations not getting the ball in the hands of our best players. Maybe experience and time and patience will solve some of these game day frustrations but most likely I will not be very happy with this O imitation of everybody else because to be elite it requires players we historically cannot recruit (QBs and big athletic lineman).
By the way I like the way our D is progressing, long way to go but reasons to have hope.
