171 ... that's the number of tackles Higgins had last year. He doesn't do that if those guys aren't doing their jobs.
You're right that we weren't getting quite as much pressure on the QB as is ideal. However, part of that is also attributable to the fact that our front-7 had some significant losses from the prior season ... and it can be a transition to get the pieces to fit together right the subsequent season. At the very base-level, guys are expected to do their jobs and do them consistently. The guys did just that! Now they have to take the next step since there is so much personnel continuity going from last season to this season.
Hurkett may not have had a sack ... but he went from seeing far fewer snaps and getting 15 tackles ... to being our top back-up DE and having 52 tackles and 6 TFLs (along with 1 INT).
I wouldn't say that Craig took a step back. It's just a different challenge when the OL is preparing for you ... rather than having them worry more about a guy like Van Ness. It was Craig's first year as a true starter at DE. He was the top backup the before ... and acquitted himself quite well.
If you look at Adrian Clayborn, he showed some really nice flash in '07 as a top backup at DE. Then, in '08, it was his first year starting ... and he was really a really strong contributor (and consistent) ... but the "flashy" numbers just weren't there that season. However, in '09 ... that's when things really seemed to "pop" and "click."
I frankly think that the absence of Noah Shannon on the interior was felt more (last season) than folks recognize. Without a productive veteran like Shannon to force extra double-teams ... that made it so that more attention could get paid to the DEs.
Anyhow, given that we "lost" so many quality guys from the '22 squad ... Waggoner, Van Ness, Shannon (due to the gambling thang), Benson, Jacobs, and Campbell ... that's a lot of experience and fire-power that we didn't have returning. What's more ... that's a lot of experience and fire-power that didn't return ... many of whom still had eligibility.
