The First Four has been around since 2011 and features the last four automatic qualifiers and last four at-large bids playing to whittle the field from 68 to 64. This year will see two 16-seed vs. 16-seed matchups and two 11-seed vs. 11-seed matchups, but don’t write these games off because they involve double-digit seeds.

NCAA Tournament officially begins Tuesday and Wednesday with First Four action followed by first- and second-round games on Thursday and Friday as part of a rollercoaster opening week that will see the 68-team field quickly shrink to a Sweet 16 in the span of six days.
