Yes, they are building this team with the draft/develop mindset. All those draftees are expected to improve with experience and being apart of an NFL Weight program.
As for Tackle, I don't see a starting need, but more of a future one. They are going to sign, a veteran swing Tackle when Tyron misses his usual amount of games and they do still have Ball who needed to get stronger. As I have said numerous times, drafting a Tackle and playing him early inside makes a lot of sense. Problem is, finding such a player.
