North Carolina schools have historically dominated in the men's NCAA basketball tournament, reaching the Final Four a combined 44 times.
Why it matters: A review of bracket history shows the longtime dominance of college basketball's "blue blood" programs — always useful knowledge when filling out your bracket — but there's always the potential for lesser-known schools to make a deep run.
Between the lines: North Carolina's tourney success is driven largely by Duke (17 Final Fours) and UNC (21), with some help from N.C. State (4), Wake Forest (1) and UNC-Charlotte (1).
