People are way too fixated on faulty concern of moving a college LT to RT.
The bluechip tackle prospects at the top of draft are LTs because they have the most complete tackle profiles and thus can add most value by protecting a QBs blindside. RTs are often a bit more brute power than LT (which requires the feet and finesse to mirror the fastest speed rushers). Sewell and Slater are LT prospects because they have the feet, mobility, finesse, AND power. The fact that they are worthy LT prospects does not detract from their ability to play RT.
Slater has plenty of experience at RT as well and Sewell has the full skillset to excel at either.
I would bet most of the best RTs in the NFL were LTs in college.
That's not to say I don't like Jenkins as a RT prospect. I do. But, I'm not devaluing Sewell and Slater at all because they are good enough to be premier LT prospects. That's the type of talent I want protecting Tua's blindside.
