We're a different team without TJ Tampa for sure (not to mention Verdon). TJ basically erased an option from the pattern on every play. Losing that takes a serious adjustment, but also, give that Memphis QB his due, he was throwing some strikes all game (short and deep).
Those 2 are probably the most athletically talented defenders. Take them off the board and all that is left is scheme, discipline, and effort.
DL. The big 3 are good, but not good enough to dominate LOS, especially once tired. Not enough depth to keep them fresh.
LB. Bacon is the best LB we got. He is a walk on and is too slow to start anywhere else. But he goes 100% all the time. Miracle he stayed healthy all year. Sawdowski is NOT the next Mike Rose, but the staff seems to be betting the future on him.
C. Pretty good, some depth. Losing TJT hurts, but the drop off isnt terrible.
S. Scheme relies HEAVILY on the safeties being excellent. And the big 3 are great. But the drop off from those 3 to next man in is shocking.
Overall, theres just too many talent holes to paper over. That said, you dont need to fix them all, but man, you gotta fix a couple. They need a Big12 level LB and some DL depth in just the worst way.
