I still think, even with Suh added, they need some edge pass rushing and probably overall LB help. With Longacre not yet a sure thing to return and Barwin in limbo they could be trying to replace 21 of their 48 sacks from a year ago (Quinn, Longacre, Barwin, Ogletree). Phillips builds his defenses on two things- pressure/sacks and turnovers.
They are probably more likely to find value at edge/LB in the first round than an OL. But beyond that, yeah, I would like to see an influx of young talent on the OL both for depth in 2018 and finding a potential starter for 2019.
