I just noticed this thread and since it was addressed to me in the OP, I figured I would respond.
I don't know where you got your info or how you did your math, but it seems a little off.
Merely going by rivals's rankings, I count 13 4 stars who we STARTED against Vanderbilt last year. I'm not counting 4 stars who were injured (like Maggit). I'm not counting 4 stars who were true freshmen/redshirts and didn't really contribute (like Carr, or O'Brien). I'm not even counting 4 stars who played quite a bit and backed up the starters (like Croom and Lane). I'm strictly talking about STARTERS IN THE VANDERBILT GAME. And I count 13 as listed by Rivals.
They are Neal, Howard, North, Richardson, Bullard, Stone, James, Smith, McCullers, Walls, Johnson, Coleman, and McNeil. The majority of these were upper-classmen as well. So, I don't see where you're getting that our staff only had 9 4 stars in total to work with last season, when they started 13 in one game alone.
How many 4 stars did Vanderbilt start in that game? How many did they have on their whole roster? Maybe by answering those questions, you'll understand why some of us don't simply blame the players (or the lack of 4 stars) for the miserable results last season.
