Even as NFL teams make a huge deal out of their discoveries from the hinterlands of college football, it's the big schools from the powerhouse conferences that dominate the draft.
Based on rosters for the opening of the 2013 season, here's a look at the best and worst selections from each of the 27 schools that had at least 20 players in the NFL at that time. So no, JaMarcus Russell - who was out of the league- doesn't make the ''cut,'' as the biggest flop from LSU.
Southern California (40)
Best: Pittsburgh safety Troy Polamalu, a borderline Hall of Famer and big-time playmaker, selected 16th in 2003.
Worst: Another safety, Cincinnati's Taylor Mays, whose lack of speed has made him a journeyman after being chosen 49th overall in 2010.
Louisiana State (39)
Best: Kyle Williams, Buffalo's versatile defensive lineman, was a fifth-round choice in 2006 and has made three Pro Bowls.
Worst: Chiefs DE Tyson Jackson, taken third overall in 2009, has had little impact and isn't even a key to the team's defense.
Best: Beating out a tremendous group of Hurricanes, safety Ed Reed, Baltimore's first-rounder in 2002, has a Super Bowl ring and a likely plaque in Canton.
