McCarthy identified that the DL is a sore point and instead of half-assing it with a passive strategy by just addressing it through the draft we signed guys who are slightly out of their prime but still very talented, while still addressing it through the draft to some extent.
Had Lamb not miraculously dropped to 17 we'd probably be looking at Chaisson/Gallimore as the future of our DL, while also having addressed the short-term with McCoy, Poe, Smith and maybe even Griffen as well.
Under Garrett the strategy was mostly to just bank on the draft and hope it worked out.
It's not a coincidence that our best seasons under Garret coincided with strong, immediate impact drafts (Martin/Hitchens in 2014, Elliott/Collins/Dak/Brown in 2016 and LVE/Gallup in 2018) while we floundered in 2017 and 2019 with mediocre to poor classes.
