(1) I happen to like CPJ and have felt all along that his scheme gave us a chance because we were never going to be able to recruit the same top tier talent that the SEC schools (and Clemson/FSU/Louisville) can recruit.
(2) Having said that, I think while he is a very smart coach and an offensive genius, he isn't perfect.
(3) IMHO, his biggest weakness is that he has his system and he tries to fit everyone into that system. (You could argue it is also a great strength, I suppose...). The difficulty with that approach is that when we face adversity, CPJ has a tendency to double down on his system and not try to branch out to try other approaches that might work well agains the defensive schemes he is seeing;
(4) Most any running offense is going to suffer when the other team puts 8 (sometimes 9) in the box to stop us. That is what has happened to CPJ and his scheme cannot defeat that without a viable passing attack. We have had 3 good seasons under CPJ, 2008, 2009, and 2014. In 2008 & 2009 we had BeBe at WR and last year we had Smelter & Waller...all NFL caliber WR's. In years we don't have that, we flounder. (No, don't bother quoting me overall offensive stats which are piled up agains the likes of Syracuse or N C State....look at the offensive results against the good teams on our schedule...VPI&SU, Miami, Georgia & Clemson.)
(5) There's no real magic or rocket science to #4 above...I think it is true for just about any offense that if you become too one dimensional, good defenses can shut you down. You can get away with it against weaker teams, but against good defenses, you MUST become diversified, or you look like we did against VPI&SU or Miami. Against UGa we have had decidedly more success than this theory would argue for, but it holds quite well agains the other good teams on our schedule. (It is also true that our success against UGa in some years was predicated on successful passing, as was the case in 2013 with Vad Lee).
So, overall, I like CPJ and like his system, BUT I think he can be too stubborn about fitting into his way of doing things, and I really, REALLY think he tends to ignore the passing game far too much, and refuses to ever subscribe to the idea that you might need to pass to establish the run.
Teams are following #4 against us this year. I don't think it is the O line screwing up that is hurting us nearly as badly as the lack of a passing game. Want to back Cash off our center every play? Throw and complete a few passes...that'll pull him back off the LOS. Thinking that somehow just blocking better will solve this is ...not right, imho. We can stumble to another 6-6 type season that way, but if you really want to rebound in a big way, I think CPJ HAS to establish a passing threat.
Oh, one other thing I will give CPJ credit for. I think he wants to win more than any of us on this board, and I do believe he is willing to try to change things to get there. So, while I reserve the right to criticize him, and think he has indeed been out-coached the last tow games, I still think highly of him and wish him (and us) well.
