Can't beat Duke? The ninth-ranked Tar Heels fell behind by three goals early but came storming back to defeat the Blue Devils for just the second time in the teams' past nine meetings.
Can't compete in the ACC? UNC (6-0, 1-0 in the ACC), which was 2-13 in the conference in its past five seasons, beat a team that had just downed fifth-ranked Maryland less than three weeks earlier.
Can't run with a higher ranked opponent? The Tar Heels had folded like origami once they hit the meaty part of their schedule in past seasons.
But after racking up a perfect record against mostly cream puffs to start this one, they showed superior poise down the stretch against the nation's fifth-ranked squad and have a ton of momentum heading into a stretch of games against highly ranked opponents.
"For the players, obviously, with an ACC game where we've been very woeful over the past five years, and against a top-10 opponent, it was a chance for them to feel good about themselves in terms of effort in beating a good team," said UNC coach John Haus.
The players, who erupted in an elated celebration at game's end, throwing their sticks in the air and hugging on the field, said the win was a big boost.
"We're definitely rolling," said junior midfielder Austin Garrison, who scored three goals, including the final one with 1:14 remaining that sealed the win. "And confidence-wise, this is huge for us to beat a team that's above us."
After committing numerous unforced turnovers that led to failed clears and limited their looks on offense, the Tar Heels trailed the Blue Devils (3-2, 1-1) 4-1 at the end of the first quarter.
But in the second quarter, they pulled themselves together, holding Duke scoreless with a staunch defense that forced steal after steal and rattling off four unanswered goals that gave them a 5-4 lead with 6:33 left in the first half.
