I can deal with this response. I appreciate the reasoning and effort.
A new set of points built on the last ones:
1. I also have doubts about CPJ ever having a good defense here, and believe it could be due to exactly what you say (more practice time and scrimmages against our offense and against scout players who fit our specialized offense). BUT, I also have doubts about my doubts! ie I'm willing to acknowledge there's a chance our defense could actually be good with better coaching (and maybe (hopefully) a few key improvements in personnel). I recognize that our last 3 DC's certainly aren't among the top of the profession or had unquestioned success at other stops with equal talent. If that were the case, the case for my doubts would be much stronger. But, that being the case definitely leaves a hung jury. We cannot say with any level of confidence that if we had a DC who was proven, then we could eliminate that variable. But, that is still the biggest variable in our equation! If we had a good DC, could we have a good defense at GT under CPJ???? This is still the big question. I don't think ANYBODY (on earth) knows the answer to that, even CPJ himself. I think he thinks he can have a good defense, which is why he's done what he's done. I have a lot of hope for this Nate Woody possibility. If he works out, we have a better program instantly without having to change anything else (like new majors and crazy stuff like that). But, I had a lot of hope for Al Groh too, so my hope could very well be misplaced. We'll have to wait and see, won't we. The proof will be there one way or another in a couple of years ... which brings up the next point...
2. What is proof?? You bring up an excellent point in #1. Extremely important point! For any productive discussion there must be agreement on definitions, measures, and such (as much as possible). I think we can achieve that in this discussion and then move on together as GT fans hoping for success. Here is the bottom line on this for me: POINTS PER DRIVE (ppd) and/or YARDS PER PLAY (ypp). These are the best way to determine success. It takes out other variables as much as possible such as defensive scores, special teams, field position, etc. And, it's all about competition, so it's a ranking rather than a raw stat. Doesn't matter if we have 700 yards of offense if everybody else has 800. If we're in the top 30 in offense, that's a good offense, and the same goes for defense. Now, a lot of people are talking about FEI. I don't know exactly how that's calculated, but I think it's an efficiency stat (so, ppd and ypp) that is adjusted for strength of opponent opposite side of the ball. I don't care about the other stats. I don't care if we have 0 yards passing or 400 yards passing as long as we're more efficient that the competition (because that means we're winning on that side of the ball). I don't care about 3rd down conversions or turnovers as long as we compare favorably in defensive efficiency with our competition. I think the reason people pointed to 3rd down efficiency last year is that's where it seemed we were had the most glaring weakness which, if improved, would ultimately improve what matters - defensive efficiency. Turns out it didn't, because we improved 3rd down dramatically, but we still were in the 60's in efficiency. The best explanation for this would be if we gave up more on 1st and 2nd down (so no need for 3rd down conversions), but I'm not sure. And, people think our offense was decent because we were in the 30's in offensive efficiency. So, nothing else matters. According to the best data we have (and thus most objective evidence) our offense was significantly better than our defense, again. And, looking at the long run of CPJ's career here, this is the consistent result - we have an upper quartile offense and a bottom quartile defense. Again, make it simple. The simplest, and best way to determine success is with one of those FEI type stats. So, bottom line, my proposal is that we (me, you, and everyone else) judge the offense and the defense by these efficiency stats like FEI. Wherever we rank in those determines how good we are on that side of the ball (and the appropriate level of satisfaction we should have as fans). Again, the evidence will be there one way or another in a couple of years, and we'll all be able to look at it and decide.
3. Actually, there's something overarching even this second point. Wins/Losses. In 2014, we didn't have a great defense, but we had a phenomenal offense and thus had a great season. So, even if the DC doesn't work out, if we end up having good to great seasons on the record books, we will be happy and satisfied with CPJ even with a crappy defense. I think the W-L record should always be taken with a grain of salt - that grain being the objective stats of point #2.
4. I think the passing game is fine, philosophically. When we have a good QB and a good WR, our passing stats are really good (I'm talking about efficiency, which is all that matters). So, if that's the case, then the problem there is not the plan or coaching, but the personnel, plain and simple. I don't have much hope that Marshall can be the answer to this at QB, but we still may be able to be good enough offensively to win a lot of ball games with him. He can be special in other areas. I look forward to better days in the passing department when we get a better passer of the ball under center.
