Duke, Michigan St. and Purdue top board following annual NBA exodus

The deadline for underclassmen to pull out of the NBA draft has passed, with only one bewildering decision to turn pro: that of Mississippi State point guard Dee Bost, who bailed on his final two seasons for life in the lesser Euro-leagues. JaJuan Johnson's return to Purdue and Jimmer Fredette's to BYU put their teams near the top of my post-deadline Power Rankings, which are a slightly more reasonable endeavor than the rankings published the morning after the national title game. I reserve the right to tinker with these by October, but I imagine my preseason top 32 will look a lot like this one:
