Then you haven't done your research. And, all you are doing is perpetuating the myth that it takes at least 3 years to develop an OL in the SEC. The truth of the matter is that it depends upon the player. the blocking scheme, and more importantly the level of coaching they receive when it comes to them being ready to play in the SEC.
The blue bloods in the SEC are Bama, UGa, LSU, and TAMU. Their OL depth charts, both starters and backups, are sprinkled with FR and So.
Bama - starting 2 SO with a FR backup
UGa - starting a RS/Fr with 2 RS/FR and 1 FR as backups
LSU - starting a FR and a SO with 2 RS/FR and a SO as backups
TAMU - starting 2 FR with 2 FR and 2 RS/FS as backups
