It's surprising looking backwards, but with scarlet tinted glasses its not as surprising looking into the future:
2005 - Stud transfer
Sylvester Mayes & All-MAC BG transfer
Ronald Lewis (rumored to be the best player on OSU's team in 2004 while he sat out a year for transferring) join team and lead buckeyes to another 20 win season and make noise in the tourney
2006 - 5-star
Daequan Cook convinces 5-stars
David Lighty and
Mike Conley to come to OSU. The NBA age limit forces otherwise #1 NBA draft pick Greg Oden to go to college, and its a no brainer that he join his AAU teammates (Cook, Lighty, Conley) at OSU. Drew Lavender coming to OSU from OU is simply icing on the cake.
Raymar Morgan is also a strong possibility.
2008 - Top-25 frosh
BJ Mullens has already committed, and other top national talent is located nearby with interest in OSU.
