I think you play this draft at the intersection of its strengths and their needs. Maybe they draft a tackle on day 3 but I think they can be positioned to go find a LT of the future in the 1st-3rd rounds next year. Having a 1st round pick back will give them flexibility. Hopefully Whitworth gives them 32 quality starts at LT the next two years. Drafting a LT in 2018 that can learn from Whitworth for a year would be ideal.
I think it's much more likely they draft a center somewhere in the 4th-6th rounds this week since Sullivan is just a one-year stop gap. Immediately upgrade from Rhaney, see if he's a long term developmental option, and if not dip back into the draft a little higher next spring.
