Not #1 in any major category, apparently, but very high in so many categories that he edged out the rest.
I don't know how much you can quote from a pay site and still be within "fair use" boundaries, but I trust this will be OK (part of the intro before you have to click to see the rest):
The senior forward finished the season with a 127 offensive rating, which was third in the country among players that used at least 24 percent of their team’s possessions. He got there by making 61 percent of his field goal attempts and 78 percent of his free throws, which produced a true shooting percentage of 64.9, easily a career high and the 25th-best figure in the land.
He also produced on the defensive end. His defensive rebound percentage of 28.5 ranked 13th in the country, and he produced solid block and steal percentages of 5.5 and 2.2 respectively. As a result, he racked up 18 game MVP’s over the course of the season, good for fifth-most in the country.
