Definitely lack depth at T for sure. It was an area I wanted to improve in via draft pick regardless of Brown but he makes the question a larger question mark. I thought Mekari played T for us originally then moved out to C after problems there or am I mistaken? I could definitely see Mekari in the mix for RT though if we moved on from Brown depending on our plans.
So I agree with you here that you'd think we would be targeting a OT early but I also don't think that's a decision you make either. The draft can turn different directions and you can't trade a player assuming you can land a guy because that is the exact strategy that causes reaches. I think if anything the Ravens would decide to move Mekari or Tyre to RT to compete. If either of these occurred then I could see Skura re-signed in a move to keep someone around at least familiar with the offense to compete at C. In this hypothetical I think it would depend on where the Ravens think Tyre & Mekari fit best compared to our other options in Powers, Bredeson, & TCC. And to your point, that does suck we don't have a legit option to fight off a RT rookie--you don't want a guy to come in and just expect to win the job by default.
So I do think Brown Jr would land us a haul for numerous reasons, those being a) he is a proven commodity vs. unproven rookies that can bust or take time to develop, b) he could make an immediate impact vs. rookie growing pains but c) he would also cost more because the Ravens clearly value him and would be devoid of true options at RT if traded & therefore the premium for him would naturally be higher. You're not wrong though that there are reasons for teams wanting him, but there are reasons we would want to keep him too.
For me, whether we trade Brown or not doesn't matter--if we do, awesome because it means we got a haul because no way in Hell would we just hand him over for peanuts when it will create a hole for us and a decent-sized hole at that. If we don't trade him then awesome, we have an awesome RT for our team who can protect Lamar.
