Mattison was the final pick in the 3rd round, taken after Spielman had traded down 4 times. I still don't like the pick since they don't use him and a guy like Boone is just as good, but Spielman at least didn't take him at the top of the 3rd. Perhaps you're having flashbacks of when the Vikings traded up in the 2nd round to get Toby Gerhart? (While AP was in the midst of his prime!) The collapse of the DT spot started when Shamar Stephen was given a 3 year deal to play 3 technique despite having zero ability to rush the passer. And then they ignored the position again in 2020. They completely relied on the development of Jaleel Johnson, Jalyn Holmes, and lesser guys like Watts and Mata'afa and they fall flunked hard. I think the days of spending 3rd/4ths on D-linemen and letting DL coach Andre Patterson coach them up is over - they need to spend high draft picks on them. As for the LBs, re-signing Barr was dumb, but they haven't spent a 1st-3rd on one since Kendricks in 2015 (and he's worth every penny of his extension). They've mostly added Day 3 picks to the LB corps (ironically our best 3rd LB by far was a UDFA).
