I haven’t been impressed with the colt lb’s for a long time. To me the biggest needs are another big dt, and lb, maybe one that is a little bigger and has pass rushing skills. That’s where I would focus the top 2-3 rounds. As always, if a player you like isn’t there at those positions, trade down and get more picks.
IMO, yes, it could use an upgrade, I don't see an elite LB on our squad but given the pass happy nature of the league, our LBs are built for where the league is heading to be good enough, like you said. If a team goes jumbo, 3 TEs with 5 OL or 2 TEs with 6 OL and tries to run it down our throat, we don't have a thumper of a LB or DT depth to disrupt that kind of game plan, unless we get ahead and play ahead on offense, which has not been the case since the Andrew Luck days for most of the time. But if they go 4 wide, we have the lighter bodies to keep up.
If the Titans go with that game plan, I am afraid we are going to have to worry unless everyone plays with "perfect" gap integrity 80-90% of the time, which typically doesn't happen.
