Agree with all the above. Especially LT. Kid is solid, demands a lot of attention. But he's still not firing on all cylinders. Our great DTs used to change game outcomes. Outside of the worst game I've ever seen (UVA last year), he has only had a marginal impact on games so far.
In general, pressure up the middle has been our Achilles heel this season. We push the pocket well. But we're not getting enough penetration. I have to believe we'll overwhelm UNC's IOL and former Cane Gaynor. But it will hurt us vs Clemson and FSU.
As far as DEs go, some of it is scheme. They have a lot more responsibilities than a Manny or Steele defense. And our blitzes are coming from all over the place now, so when we get to the QB, it's often not from the front 4. Some of it is offenses protecting more and better. But yeah, outside of Mesidor and Bain, I haven't see the other guys getting to the QB quickly enough.
All that said, if we see it, then Mario, JT and Salave'a see it. I have zero concerns that they'll address this one way (development and HS recruiting) or another (portal).
