This still does not explain the complete failure of a QB school USC has been in the NFL!!
Mark Sanchez, Carson Palmer, Matt Leinart, Sean Salisbury, Rodney Peete, Pat Haden, Matt Cassel, Bill Nelsen, Pete Beathard, Vince Evans, Paul McDonald, Todd Marinovich, Rob Johnson AND John David Booty.
Don't turn it around... the argument is that USC quarterbacks historically suck, big time. THAT is irrefutable.
