I am not surprised to see Womack at RT expecially. I am surprised to see Cotton back at Guard but that may be the only place open for him so he better adjust. I think he certainly can, Last year was a good experience for him, he just needs to build on that.
As for Womack when we signed him it was thought he would be a feast or famine recruit. The kid was absolutely massive. Size after all does matter but the question was could all that mass be controlled. I started reading positive buzz about him last year and seeing him lined up at 2nd team left tackle was confirmation that he was doing very well.
I think it's a long time till fall and he will certainly face a furious battle for that job so if he beats them out you can rest assured that Womack can get the job done.
