Interior DL often gain an advantage by getting low, getting leverage. I think it is therefore tougher for very tall, rangy guys to play guard; their length can be a disadvantage. Because of where DEs often line up, an athletic tackle is, however, actually advantaged by length/wingspan. I think PJ and Callahan will play the best five on the OL, but probably make reasonable attempts to match positions with body types. Carroll was a good run blocker this year, but, I believe, a slightly below average pass blocker. I'll bet he would prosper inside, and that would open up RT for rangier Lewis and/or Guedet. I don't know why, but I could see Guedet moving inside before Lewis.
