COPLEY — Tuesday night’s game ebbed and flowed for most of 27 minutes.

Then it was all flow for Copley.

The Indians held visiting Jackson without a field goal for the final five minutes and pulled away for a 65-53 win in a battle of two Division I heavyweights that are building a nice little rivalry in high school boys basketball.

“That’s a big win for our program,” Copley coach Mark Dente said, “to get a perennial state power to come to our gym and beat them by double figures.”

Two years ago, Jackson knocked off Copley in a district semifinal on its way to a state championship. Last year, the Indians beat Jackson in a regional semifinal.

If Tuesday night was any indication, another tournament meeting would be fun.

Senior DJ Jones scored 17 points to lead four players in double figures for the Indians (12-2), who lead the Suburban League American Conference.

“It kind of felt like a tournament game,” Dente said. “Jackson is so good. … We tried to stay out on the shooters as best we could and not help, and sag a little bit on the ball. Holding a team like that to 53, it worked.”

Senior Anthony Mazzeo served as Jackson’s playmaker and led the Polar Bears with 17 points and four assists.

Jackson (12-3) trailed by as many as 11 in the first half with deep threat Trent Jones in foul trouble. The Polar Bears rallied to take the lead twice in the second half but seemed to run out of gas.

“I think it was a good game for us on the road,” Jackson coach Tim Debevec said. “That’s a team that was in the regional final last year. You almost have to be perfect.

“… We better learn from this and not do it again on Friday and down the road.”

Lesson No. 1: Boxing out. Copley pounded Jackson 40-19 on the boards, and 15 of those rebounds came on the offensive end for the Indians, who had three looks each on two separate possessions late to help them put the game away.

Sam Emich, a 6-foot-6 senior, had for 16 points, 10 rebounds and three blocks, and 6-3 sophomore AJ Campbell added 11 points, 10 rebounds and four assists.

Copley senior guard VannAubrey Thomas totaled 15 points and eight rebounds — five of them offensive. The fifth Copley starter, junior Tyson Durant, scored six points before fouling out. The Indians rarely subbed and didn’t get a single point off their bench.

Jackson led 48-47 with 7:18 left when Jones drained a 3-pointer from the right corner.

The lead was short-lived. Emich answered with a quick-trigger 3 of his own on the ensuing possession.

“Honestly, I really wasn’t thinking about it,” Emich said of his momentum-swinging shot. “I just kind of stepped back from the 3-point line and let it fly. I was like, ‘Oh, it went in. We’re good. Let’s get back and play some defense.’ ”

That they did.

Leading 52-51 with less than five minutes left, the Indians held Jackson to 0-for-5 shooting down the stretch. Jones also got a steal and breakaway bucket in what became an 11-0 run for the Indians.

Senior Will Hyde totaled 12 points, six rebounds and three blocked shots for Jackson, and senior Hayden Junker scored 10 points before fouling out.
