Trailing late in the second half Saturday at McCamish Pavilion, Georgia Tech needed a spark. Cole Kirouac delivered.

The 7-foot freshman found himself unguarded inside the arc on the left side of the court. Without hesitation he bolted toward the rim, took flight and slammed home the ball with two hands to tie the score at 46 with seven minutes left on the clock.

Kirouac’s dunk brought many of the 5,978 to their feet and changed the energy in the building while the Yellow Jackets threatened to lose to the worst team in the ACC. Instead, Tech took the lead shortly after Kirouac’s play and never trailed again in a 65-53 victory.

“Originally, it was just supposed to be a handoff. I saw my man sagging off. I just took one dribble, went up and dunked it,” Kirouac said. “I feel like I was pretty tired in that moment. I feel like that energized me a lot. I think we had energy as a team, but I feel like it probably boosted it a little bit.”

Said Tech coach Damon Stoudamire: “That was a heck of a dunk he had. That ignited us, ignited the crowd. Proud of him and happy for him.”

But the Jackets (10-5, 1-1 ACC), the ACC’s second-worst team in the NET, found themselves in a dogfight for much of the afternoon despite leading by 10 late in the first half. The Eagles (7-7, 0-1 ACC) had momentum on their side and led by four with 9:14 to play before wilting at the end.

Tech guard Lamar Washington flirted with a triple-double by finishing with 17 points, 12 rebounds and five assists. Kowacie Reeves scored 16 and Baye Ndongo had 10 points and eight boards.

Twenty of Tech’s 65 points came from the free-throw line. The Jackets also had 23 fast break points — Boston College had none.

“We’re a good team,” Washington said. “When we play together and we play with confidence and we play how we’re supposed to play, we can — I feel like we can beat anybody in the nation.”

Tech was sluggish and sloppy at the outset, suffering through a field goal drought of 6:04 while missing nine of its first 10 shots. But a Ndongo layup followed by a Kam Craft 3 from the right corner tied the game at 11-all a little less than eight minutes into the fight.

Tech had six assists on its first seven made shots at that point.

Fleming’s score began an 10-2 Tech run that also included a Fleming dunk and two Fleming free throws that upped the lead to 27-17.

But the Jackets wouldn’t score the rest of the half and had to settle for a 27-24 lead at the break. The Eagles, despite shooting 9 of 34 from the floor, ended the period on a 7-0 run to close the gap.

“I was actually disappointed the last three minutes of the first half because BC, they’ve played a lot of games where they just rock you to sleep,” Stoudamire said. “You’ll feel like you’re in control of the game and then all of a sudden you lose a rhythm offensively, and then they start scoring some buckets and they hit a bank-shot 3 and you just have all kind of things start happening, and that’s when the game turned. The momentum of the game, it shifted. And we couldn’t find it back offensively.”

A back-and-forth first eight minutes of the second half saw Boston College finally tie the game at 36 before Tech squeaked ahead by four thanks to two Washington free throws and a Reeves layup.

The Eagles responded with a 7-0 run and took the lead on a Donald Hand Jr. 3, and then went up 43-40 on Chase Forte’s layup at the 10:33 mark. Boden Kapke’s putback after a missed free throw gave BC a 46-42 edge 64 seconds later.
