GG, I’m not so sure this is the reason.
Take a look at Pitt’s rankings in run defense, sacks, and tackles for loss from 2015-18.
Rushing Defense
2015: 55th
2016: 40th
2017: 16th
2018: 41st
Sacks
2015: 102nd
2016: 16th
2017: 6th
2018: 74th
Tackles For Loss
2015: 120th
2016: 41st
2017: 31st
2018: 106th
Each category has its best two seasons from 2016-17 and its two worst seasons in 2015 and 2018. Going off of this, if it were truly the front seven, I’d argue that the pass defense would also have their best seasons in 2016-17 because they’re getting more support from the front seven. However, take a look at the rankings,
Pass Defense
2015: 24th
2016: 54th
2017: 127th
2018: 105th
There’s really no correlation between the pass defense and run defense; It gets progressively worse each year until they’re in the 100+ range the last two seasons. In fact, the secondary had its worst season (2017) the same year the front seven performed the best in those categories. You could play devil’s advocate and say the good run defense (less rushing attempts) and sack (more passing attempts) numbers in 2016-17 are misleading because teams passed the majority of the time against us, but that still wouldn’t account for the TFL numbers. With these, I’d be more inclined to say we had poor secondary play and an average front seven the past four years.
Why I felt the need to do this at midnight, I have no idea.
