I understand the sentiment, but I don't see how you can honestly include RT in that. 3/5T and ILB are fine, we've got options already there and we have a history of finding guys late/undrafted to fill those spots adequately. But unless we plan to move Lewis to RT we currently can't feel comfortable with a competition between 2 guys that spent last year on the practice squad for the starting job and Hurst. Nobody said that means we have to take one early, the one you responded to was just pointing out that it wasn't addressed at all. We have a history of finding solid RTs in the mid rounds, not UDFA. Of course if Lewis is moved out then this is all irrelevant, but we can't just assume that he's going to.
Even if we aren't looking for a starter, depth on the line was still a big problem last year, even before we lost two starters this offseason.
