I was using the LSU analogy not as a comparison between the two units, but as an analogy stating what is being said doesn't tell the whole story.
What you've said is true. Yet, it doesn't tell the story in its entirety.
The LG and RT have two years of playing experience. Last season, both saw action over 75% of the games played. Both saw action in 50% of the games played the previous year. The C played in 10 of the games in 2012-'13.
It's not a case where the guys stepping into those roles are "green."
Stepping back just a tad to the paste you provided earlier with this caveat that I put about as little value on offensive lineman rankings as I do QB rankings, the author says:
Alabama hasn't recruited at quite as high a level at OL as it has in other units. Yes, former all-world recruit Cyrus Kouandjio is still in the mix, and yes, All-American Chance Warmack was, like a few of this year's probable starters, only a three-star recruit.
Two of these three new guys on the line were ranked higher than Chance and he writes "like a few of this year's probable starters." Simply not true. That player, the right tackle, is the one I put the notation beside in the post just above this one.
