"I think maybe (if) we didn't get the techs, we probably still had a chance to win," Fair said.
This one always seemed destined for a tight finish, even after Duke appeared to take control down the stretch.
The Blue Devils scored on six consecutive possessions, keyed by Cook's 3-pointer that pushed the lead to 53-47 with just under 7 minutes left.
Three trips later, Parker soared to dunk the rebound of Hood's missed 3 — which restored the Blue Devils' six-point lead and sent the Cameron Crazies into earsplitting delirium.
But Ennis followed with a layup and Grant hit a jumper in transition, and things stayed tight until those technical fouls.
The game again matched the two winningest men's coaches in Division I history in Hall of Famers Krzyzewski and Boeheim — who, by the end of the night, combined for 1,924 victories.
Round 1 went to Boeheim earlier this month in a game for the ages, with the Orange claiming a 91-89 victory in overtime after Duke's Rasheed Sulaimon hit a buzzer-beating, tying 3 at the end of regulation before 35,446 fans at the Carrier Dome.
There were about one-quarter of that many at 9,314-seat Cameron — but the 74-year-old building rocked all night with a ferocity usually reserved for the annual visit from North Carolina.
"Another great game. Different from the first one because it seemed like both teams were scoring easy up in Syracuse, and today it was really difficult to score," Krzyzewski said. "I don't know how either team could play any harder."
And from the opening tip, this one felt like a continuation of that OT thriller — with players from both sides turning in highlight-reel plays, from Marshall Plumlee's vicious dunk of a missed 3 by Sulaimon, to Ennis' emphatic block of a layup by Cook.
Syracuse maxed out its lead at nine on a 3-pointer by Duke transfer Michael Gbinije midway through the first half. The Blue Devils rallied to tie it at 26 at the break on Sulaimon's fast-break layup with about a minute left, and it stayed tense the rest of the way.
