Selection Sunday is here. The selection committee has made almost all of its decisions, the bracket reveal is hours away, and soon enough, the field for the 2017 NCAA tournament will be set. However, there are a few decisions to make. A detailed breakdown of the field reveals that, of the 36 at-large spots available, 31 or 32 are locked up; four or five bids are still up for grabs, with nine or 10 teams hoping to snatch them and run to the Big Dance. The most polarizing team in college basketball is, after a season of controversy, tumult and underachievement, finally playing near its best. Duke always had the pieces to be a title contender, if not a title favorite, and those pieces have clicked into place, first in early February, and now once and for all in the ACC tournament. On Sunday, the Blue Devils made ACC Tournament history, winning four games in four days.
