Of the 5 OL positions guard i's the easiest to change. The reason they didn't do this last year was for that dreaded C word. Massie and Long worked out together all off season. Since they could not move Massie, Long was the only stable force on the entire OL, with the young Grasu on the other side. This the reason we didn't go 0-16. As for this year, all potential starters were on the system last year, so it's less painful to swap all pro guards. Lastly, the muscle memory is also greater the further you move outside, that's not going to be an issue as Long and Sitton both excelled at those postings previously.
