It probably has more to do with the academic drive of college basketball players (most of whom think they will be making their living playing their sport professionally here or abroad) versus college football players (most of whom know they will not), and institutional failures to educate big name athletes (who colleges fear will bolt if academic standards are too high).
The scoring crown may be viewed as ornamental to die-hard basketball fans and analysts, who recognize that Anthony won the title by playing somewhat less efficiently than Durant.
