re: Most productive 3* or lower recruits at your school since the prevalence of

Josh Allen was a 2*
Bunchy Stallings was a 2*
Wesley Woodyard was a 3*
Danny Trevathan was a 2*
Benny Snell was a 3*
Randall Cobb was a 2* (bumped to 3* late)
Bud Dupree was a 3*

Calvin Taylor was completely unranked
Jamar "Boogie" Watson was a low 3*/2*
