In 2016, the Pats finished tied for 16th in sacks with 34, with Sheard, Long, Nink and Flowers accounting for 20 of those. Half the league had more sacks than the Pats, but only half of that half even made the playoffs. And the Pats won 17 of 19 games, including the SB.
Before the start of the 2017 season, the Pats lost Sheard and Long in free agency and Nink to retirement. They also lost their top DE/OLB draft pick, Rivers, to a torn ACL in the pre-season. They lost Hightower's contributions for all but five games. They even lost Trey Flowers for two games with a rib injury.
They've essentially replaced all those guys with a motley assortment of UDFAs and other "Unheraldeds", including Kyle Van Noy, Adam Butler, Lawrence Guy, Deatrich Wise, Eric Lee and Cassius Marsh.
After 14 games, the Pats are currently tied for 16th in sacks with 32, and are on track - again - for the #1 seed and HFA through the playoffs.
Nevertheless, in 2018, like every year, it seems clear to some that the Pats need to make "a pass rusher a priority in the draft".
In order to ... what? Put them over the top?
