Yeah, I joked upthread that Davis would be Public Enemy #1 now that Smith is gone, but he deserves it at this point. OSU recruits the same level of talent at LB as it does every other position group, so the reason LBs are so far behind the rest has got to be poor coaching. Davis's NFL experience isn't translating to the college game for whatever reason. Without significant improvement, he will not be the position coach in 2019.
I'm actually feeling really good about the secondary. Okudah and Sheffield at corners, Fuller and Wade at safety. That works for me - assuming Wade can make the transition to safety. He's a beast that should be on the field, and I can see him developing into a ball-hawking safety in the mold of Malik Hooker.
