Oddly enough, today's Columbus Dispatch has a story about the Ohio State class of 2003 with 14 players including one 5 star, six 4 star players, seven 3 star players, a top 25 class.
Four years later only 1 player remains. Two used all 4 years of eligibility, three left early for the NFL, two had career ending injuries, and seven left the program for other reasons. Included in that seven were four 4 star players.
