Great OP, and I have been speculating on this OL for quite a while, and am awed by that possibility, truly an amazing upgrade. And, as one poster pointed out, we would still have several starters from the current team available for depth, some should be very good from added experience alone by then. And with our Remington Candidate as a senior leader (imagine that, a Joker recruit and only rated a 5.4 coming in) next year we could be much improved just by next year. And if we do get a five star Freshman in 17 he probably would play, (I think Young plays next year) very few five stars redshirt, (although Florida did have a 6' 5" 330# FIFTH YEAR five star playing against our 265# walkon Joker's first year) and rightly so, Warford was only a 5.6 and to redshirt him would have been a huge mistake.
One "correction" I would make to the OPs thread, which I have pushed a lot, the numerical ratings for Rivals are much more definitive than the star ratings, (and should be used whenever available, IMO) AA could be a 5.5 and still be a three star, but he is a very near four star (and should have been one from all indications), and Leavitt is not just a four star, but a 5.9 four star. Also Young is already a 6.0, one step from a five star.
So, without revised rankings (which should be a definite possibility) we could start a 5.7, 5.8, 5.9, 6.0, and 6.1 OL as soon as 17.
By the way, by the numbers alone (doesn't mean they would be better) that OL would rate higher than the much ballyhooed Bama starters on the OL that has had a huge influence in Bama playing for the NC coming up shortly------and they are favored in large part because of that OL.
Their Heisman winner didn't do it by himself.
