Running the four corners, the Lady Huskies took a 42-33 win over the Lady Rangers in Tuesday's District 1-A championship game at Daniel Boone.
"Sometimes you use things from people you don't like," Buchanan joked.
The offense came as no surprise to the other side, but there was little the Lady Rangers could do to stop them.
"I knew they were going to do it," Unaka coach Kenneth Chambers said. "They're good at it. Once they get the lead, they're hard to beat where they handle the ball so well."
North Greene (22-10) will host Jellico in the Region 1-A quarterfinals. Unaka (23-10) will host Washburn.
That lead came in the third quarter when North Greene outscored the Lady Rangers 14-5. It helped overcome a first half which the Lady Huskies went just 1 for 12 from 3-point range.
Tournament MVP Jacinth Crawford paced the Lady Huskies by scoring 13 points, followed by Breanna Savage with eight and Katilynn Franklin with seven.
"We finally made a few shots," Buchanan said. "Normally, 42 isn't enough (points) to win the game — but it is when you got the hearts of these kids and want to stop people."
The Huskies weren't able to stop Unaka's Myah Parlier, who netted a game-high 19 points, but were successful in slowing her down in the second half. The next highest scorer for Unaka was Erika Potter with six points.
The evenly matched teams battled to a 13-13 tie at the end of one quarter. Potter gave Unaka a 22-21 lead at the half by hitting a short bank shot with 3.5 seconds left.
However, North Greene gained control and spurted late in the third quarter for a 35-27 lead.
"They went on that run, made a couple of shots, had a couple of put-backs," Chambers said. "They made a shot or two and we missed a shot or two."
North Greene 66, Sullivan North 61
The Huskies (24-8) made good on all free-throw attempts in the final 71 seconds of the second overtime to defeat the Golden Raiders (16-15).
Andy Stevens scored a game-high 21 points and tournament MVP Elijah Smith tallied 18 for the Huskies, coached by former David Crockett standout Sam Tarlton.
Turner Bailey ended with 16 after missing a chance to end the game at the end of the first overtime.
"I told the guys before the game they had the opportunity to do something that hadn't been done in about 30 years — to win back-to-back district titles," said Tarlton, in his first year after taking over from Brandon Broyles. "A double-overtime game, they showed their toughness. I'm really proud of them."
Thomas Brown hit for 27 points, which included seven 3-point shots, to lead the Golden Raiders. Matt Burk finished with 15 points.
