That was certainly true during the Tevin Washington years. I don't think that's true this year. Our defense has really done well in about half the other team's possessions in each of our losses. D held UVA to 6 points on offense in the first half yo.
In the UVA game...
the D got a pick 6
our ST gave up a KR for a touchdown
the O got a safety
That's 9 points on the UVA scoreboard that the D didn't give up, and another 7 that the D earned themselves. Wipe those 9 off the scoreboard, and give the D credit for their 7, and there's a 16 point deficit in your argument. The problem vs UVA was clearly, clearly, the offense.
