The madness continued on Friday with full action on the men's side as the field was whittled down to 32 teams.
The early window was pretty chalky before going to Colorado-Florida and Yale-Auburn in the afternoon. Colorado beat Florida with a last-gasp corner jumper that rattled around the rim, then Yale stunned Auburn.
