The way I read those records is:
A). Coach Kelly has over the last six years given us the best three rated teams of the last twenty;
B). Just imagine what the records would have been if we'd had even one good QB for a three year stretch (Chryst/ Hendrix/ Golson/ Zaire/ Kizer --- all of whom people thought would be excellent, or at least far better than they were, and Kizer an AA if he'd stayed around.) In my opinion it would have been the seven best rated teams of the last twenty.
These sorts of things are why I hold the (surprisingly lonely -- to me) opinion that Coach has been consistently generally excellent, being held back by only three things:
1). the previously mentioned diabolical bad luck of great QB prospects turning out to be emotional busts (a problem which can now be solved by Book, and very probably spectacularly solved by Jurkovec);
2). being too damm good a man in showing loyalty to certain coaching teammates, not being able to see their faults quickly, and being really reluctant to replace them (another problem that now seems to be solved, but surely at some emotional cost);
3). also showing probably too much loyalty to certain veteran players (the absolute worst case being, again sadly, the Joe Schmitt situation --- a good player overmatched in high-level games, and supported by a DC whose schemes were too complicated and "intellectual" to be comprehended by anyone else) and hard-working practice players who might not have been as functional as some younger guys who might have been practicing pretty hard themselves but couldn't get into the game-plan focus (it "feels" as though this happens to some of our receivers, and maybe RBs.)
My who-cares opinion is: Coach Kelly is great --- probably should be runner-up Coach-of-the-Year to the UCF guy. Coach will have us back "in the conversation" again next year, unless the Devil strikes our QB situation again. And thank GOD for the win vs LSU --- maybe it will get some people off his back.
