The bad side of college football recruiting was showcased by Louisville Monday night, as the Cardinals pulled their scholarship offer from commit Matt Colburn, less than two days before National Signing Day. Bobby Petrino’s program received some serious criticism from recruiting analysts following the news, including this rant from a Rivals.com writer that called for all South Carolina high school players to boycott Louisville. Even a Cardinals’ commit thinks Louisville was rough on Colburn, a three-star running back out of Irmo, South Carolina. G.G. Robinson, a three-star defensive end committed to Petrino’s program, tweeted the following Tuesday morning. Man what Louisville did to my boy Matt was messed up….. That’s awful— GG (@GGRobinson85) February 3, 2015What Louisville did isn’t unheard of, but doing it less than 48 hours before National Signing Day seems fairly classless. The Cardinals’ 2015 class ranks No. 31 in the country by 247 Sports’ Team Rankings.
