Here are our key observations from UNC and Duke women's basketball's NCAA Sweet 16 matchup in Birmingham as the Blue Devils eliminated their ACC rival.

The last team in the field and the subject of plenty of criticism the past two days, UNC put the hammer down early to win its First Four matchup against San Diego State.

After splitting their regular season matchups Duke and North Carolina gear up for a tiebreaker Friday in the Sweet 16.

Here's how social media is reacting to UNC basketball sneaking into the NCAA Tournament on Sunday as a First Four team:

A season-low in scoring plagued No. 3 seed North Carolina (29-8, 13-6 ACC) as it fell, 47-38, to No. 2 seed Duke (29-7, 14-4 ACC) on Friday afternoon at Legacy Arena in Birmingham.

The 6-foot-7, 230-pound Greensboro, North Carolina native joined North Carolina for his senior year after playing two seasons at Morehead State, one year at Western Carolina and one year at Georgia Tech. He was one of a few players who committed to the Tar Heels out of the transfer portal with the hope of providing depth in the front court.

The UNC basketball staff is showing interest in a member of the Tar Heel family in Elon transfer Nick Dorn.
