According to the Rivals database, which could be way off but it's the best I can do, here's the data on DE and DT offers since 2011:

2011: 39 offers (including Brennan Scarlett), 5 commits (Charlie Hoplins, JB Salem, Anthony Hayes, Kevin Anderson, Lance Callihan)
2012: 29, 5 (Luke Kaumatule, Aziz Shittu, Nathanael Lohn, Ikenna Nwafor, Jordan Watkins)
2013: 8, 2 (Mike Tyler, Austin Hooper)
2014: 14, 3 (Solomon Thomas, Harrison Phillips, Lane Veach)
2015: 22, 3 (Dylan Jackson, Gabe Reid, Wesley Annan)

2016: 15, 4 (Peek, Schaffer, Swann, Williams)
2017: 7, 2 (Ryan Johnson, DWP)
2018: 7, 2 (Booker, Tobe Umerah)
2019: 11, 2 (Herron, Pakola)
2020: 8, 3 (Lester, Keneley, Phillips)
2021: 12, 3 (Buckley, Franklin, Armitage)
2022: 13, 4 (Zach Rowell, Pat Caughey, RJ Cooper, Teva Tafiti)

Yes, the data are noisy, as a number of these players are out of position--the "errors" played as LBs and TEs, as best I can tell--and the more recent years include PWO (I think). 

But the general trend in terms of number of offers is probably accurate enough to say that we aren't getting enough DL because we aren't making enough offers. Take away 2011, Harbaugh's last year in charge of recruiting and the average number of offers under Hart was 15 or 16. I think a lot of the 2016 offers were made when Hart was still in charge of DL, so look at 2017 on for a comparison with Reynolds, and the average number of purported DL offers is 9 or 10.

Does this reflect reality? Or maybe the Rivals data are too unreliable to draw conclusions?
