Sure I can
It’s scheme failure vs execution failure
We have a top 10 offense and a top 75 defense right now.......
That indicates that one is clearly being coached horribly
First, the defense was a known liability going into the game. It's like playing baseball knowing the 7, 8, 9 guys can't hit for crap, but you have 1-4 guys that you know can knock the cover off the ball so you plan on riding them. Then when they suck it up in crunch time, you go yell at the 7, 8, and 9 guys for being exactly what they've proven to be during the season and ignore the guys who did the opposite of what they've proven to be capable of doing.
Second, NCAA numbers.
1. Defense: WVU is currently 44th in scoring defense across the NCAA. That is with playing scoring offenses of OSU (14th), TTU (17th), Texas (41st), Baylor (77th), ISU (93rd), Kansas (99th), TCU (102nd), Tennessee (105th), KSU (117th). Average of 73.8 and median of 93
The WVU defense gave up more than 2 total scores to 14, 17, 41, 93, and 99 scoring offenses. In those games WVU held 14 to 14 points in a half, 17 to 10 points in a half, 41st to 13 points in a half, 93 to 10 points in a half, and 99 to 7 points in a half (gave up garbage time TD and 2pt conversion w/ 0:00 on clock). None of these games involved the other team winning going away. 99 forgivable. 93 an embarrassment. Other 3 games against top 50 scoring offenses.
2. Offense: WVU is currently 10th in scoring offense across the NCAA. That is with playing scoring defenses of ISU (25th), KSU (46th), TCU (50th), Texas (56th), Tennessee (66th), Kansas (84th), TTU (86th), Baylor (93rd), OSU (99th). Average 67.2 and median 66.
The WVU offense held to 2 scores or less in one half against 25, 46, 56, 66, 86, and 99. In those games WVU was held scoreless against 25 in second half being down by just one score at half, held to 14 against 46 in second half while going in up 21, held to 14 against 56 while trailing entire second half until last minute TD and 2pt conversion, held to 13 in the first half against 66th before catching fire 2nd half, held scoreless against 86 despite rallying to outscore the WVU offense yet be saved by defensive TD, held to 10 points against 99 while opposition rallies to outscore the WVU offense. Forgivable for 46 given being comfortably ahead and for 66 given it was the first half and they really turned it on when it mattered. Ultimately the WVU offense was held to 2 scores or less in the second half when the game was on the line against 25, 56, 86, 99. That is only one top 50 scoring defense and 2 below the NCAA average for scoring defenses.
The point is that when the WVU defense was expected to be a liability, it definitely was. When the WVU offense was needed to be and expected to be a strength … it was a liability.
Third, Big XII numbers.
WVU is 2/2 in scoring offense and scoring defense respectively. That is the best combination in the league. OU (1/7), ISU (7/1), Texas (5/5), TTU (4/7), OSU (3/10), TCU (9/4), KSU (10/3), Kansas (8/6), Baylor (6/9). So few teams play great defense in this league and no team is really good at both with the exception of perhaps WVU by the numbers.
Conclusion: When it is all thrown together, I think its a strong argument that because the offense has less injuries, the "better coaching," more talent, and more returning starters it is more damning that they have crapped the bed in critical situations against very beatable opposition 3 times as opposed to the defense not having any of the advantages mentioned above crapping the bed against only one very beatable opponent and the rest being at least top 50.
