I think the guys that they did get worked out pretty well. For whatever reason they weren't able to get a top DT or another RB for example.
So they took a gamble at DT with Jeudy, RVP, and couple of developmental transfers and that didn't end up working out as well as RB luckily EJ is workhorse and was able to be the guy all year with little to no help from the backups.
In hindsight they should have kept Seagren or found another OT in the portal too.
