Much better than last year & around the same level as 2018.
That's exactly how I see it.
Look, I don't want to take a dump on Stroud. By all accounts he's a good dude, is still with us helping run the program and he recruited like a banshee!
However, for those unfortunate enough to have followed my posts during this past season, you know that near the top of my complaints about the team was the fact that Stroud wasn't a good DL technique coach. Simpson, on the other hand, is one of the best we've ever had at that staff position.
The combo of the depth we have at DT, the talent we actually do have at DE (multiple 4*s), the more aggressive scheme Manny will be running, better coverage on the back end and a LBing core with a pulse, plus Simpson's excellent training, will actually make the net efficacy of our DL improve over this past year. The DE's may not put up gawdy numbers, but we will be much stronger against the run and keeping the QB scrambles contained. That stuff is important. Forget splash, think the Moneyball approach for CFB D's.
I expect our D as a whole to take a giant step forward this year and I expect the DL as a whole to also take a step forward.
Last thought: one of the best D's we've ever had (and I feel like the youngsters don't appreciate it since they didn't experience it live) was the 91'/92' D. It was one of our best ever! Now, I'm not saying we can equal them, we 100% CANNOT equal the best LBing core in CFB history, HOWEVER, what makes me compare them to this coming season's D is similar but a slight inversion. Here's what I mean...
The net sum of the 91' D was up there with the greatest D's we've ever had, and they were elite in the secondary and great at LBer, plus, their DE's were all world (for CFB at least), but their DT's were just solid. The net result of it all, equalled a great D. In this coming season's case, with such leadership, experience and athleticism returning at DT, if our DE's hold serve, the net result should equal a top 10 D.
Last year, our starting DE's were both NFL level athletes and had their glory moments, but the net result of the whole D was meh against any O with a pulse. I could care less how splashy our DE's are as long as the net result is a top 10 level D. I think we get that next year and I think Simpson will squeeze the maximum amount of production out of our ends.
