The same argument was made by UT fans here after the 2019 season when OU lost Murray (1st rnd) and Gallimore (3rd rnd).
The same argument was made by UT fans here about the OU DBs after the 2020 season when OU lost Tre Brown and Tre Norwood, both of whom played in the League.
OU's defense improved in 2020 and the DB were a push last year. The overall point is that OU' can realize immediate benefit because they're recruited pretty well and there are two glaring inefficiencies:
- maddening personnel decisions over the last couple of years, especially in the defensive backfield.
- poor development of talent in the back 7
OU loses AT LEAST 6 defensive starters from last game:
DL Isaiah Thomas, Winfrey, Bonitto
DB Turner-Yell (possibly), Fields, Broiles
Winfrey was overall underwhelming. The Sooners have JAGs that did as well as he did coming back. Bonitto and Thomas will be missed, but if Jalen Redmond comes back and is in shape, he can give you a good Thomas impression. Grimes and Clayton Smith will replace Bonitto, and I'm excited to see both of them.
Turner-Yell was by far their best S/NB. He may come back, and if he does, I hope to see him as NB against teams that play smaller receivers in the slot and don't run much. He covers well (not great), but he doesn't tackle well in space, which is a pretty important job for a safety. OU's got several good options to replace Fields and Broiles. Both were effort guys, but should've been supplanted by more talented guys developed in the system.
I think you'll get an improvement in LB play at least with Venables coming in. LB play and development was a hallmark of his time at OU (Marshell, Calmus, Lehman, Mitchell, Ingram, Alexander, Lofton, Harris, Clayton) and at Clemson (O'Daniel, Anthony, Boulware, Simmons). OU's LBs looked lost in coverage, especially zone. This will improve.
I'm assuming the back 7 will be better because of the above points. The DL has talent on the edges to approximate the production of Bonitto and Thomas, and the DTs just need to be their JAG-selves again.
