See, the problem here is that the O-Line isnt like musical chairs. You cant just say "Mike Williams is a tackle, so clearly he can play LT". Mike Williams has always been a RT, all the way back to college. You want to plug his plodding self at JP's blindspot? Teams cannot just mix and match O-Lineman and think that there wont be a problem.
Now, if we want Womack to play tackle, he'd have to be our LT because Big Mike cant do it. That being said, Womack at least has experience at LT, I give him that. I think I'd be content if we could sign DeMulling and Womack, set DeMulling at LG and then have a training camp battle between Womack and Gandy to see who wins the LT spot.
And I'd still draft a Center and Tackle with our first two picks to further solidify our O-Line.
