The Wall Street Journal added up regular season playing time by college and the results should not be surprising. The leaders in minutes played were Duke (21,609), UCLA (18,029), Kentucky (17,159), and North Carolina (16,904) with the first three teams tied for having the most players at 16. There are not necessarily any major surprises other than a few strong programs like Wake Forest and Georgia Tech that are still up there despite falling on hard times recently.
It is worth noting that LeBron James played 2,325 minutes this past season, but is not counted because he never went to college. That total would put him ahead of Indiana and Illinois by himself.
