Going back a year further, to 2012, what do we find? Excluding Clark, Murray, Wells, and Roberts, who didn't enroll (or left immediately), and Stewart and Jarid Brown, who should have been in the 2013 class, and Tanner, who may never play, there were a total of 16 recruits, including 3 Jucos a transfer, and 12 Freshmen. Since almost all have either played, or been injured, I'm just going to divide these into 3 groups - those that have started at least one game, those that have played in 6 or more games, and those that have played less.
Starts
Laseak - 6 starts, played in 2 other games
Branz - 4 starts, played 2 others
Waters - 3 starts, played 5 others
Kendrick Smith - 3 starts, 4 other games
Watson - 2 starts, played in 4 other games
Gibbons - 1 start, played in 4 other games
6 or more games
Edmond - played in all 8 games
Reid - played in 8 games
Sebastian Smith - played in 7 games
Patterson - played in 7 games
Davis - played in 7 games
Wm Johnson - played in 6 games
less than 6 games
Schany - injured, has not played
Windham - has not played
Rodriguez - played in 1 game
Henry - injured, has not played

ESPN
They actually rated a few players this year
Starts - 2 of 6 players rated, average rating of 71.5
6+ - 4 of 6 players have been rated - average rating of 72.0
<6 games - 2 of 4 players rated - average rating of 75.5
Seems to be a slight negative correlation here
Overall, I find no evidence that any of the recruiting rankings for 2012 were correlated to how the players have done on the field.
