Manning also added team highs of seven rebounds, seven assists and four steals.
“We have a lot of depth,” Manning said. “Whoever gets it going for us, I’m going to get him the ball.”
Eric Modica led the Eagles (20-9) with 13 points, while Zaharchuk added 12 and Wes Murphy 11.
The Cardinals’ defense was a factor as the Eagles shot only 36.8 percent from the field and 22.2 percent from 3-point range.
“We were able to frustrate them,” Curle said.
Plattsburgh held a 39-35 rebounding edge, even without leading rebounder John Perez, who is lost for the season with a broken fibula.
The Cardinals continued to build on their first-half lead and took a 41-25 advantage into intermission.
Husson went on a run to open the second half and cut the Cardinals’ lead to 46-37 on a Jacob Moore 3-pointer.
But two inside baskets by Williams and one by McIntosh put Plattsburgh back on top, 52-37. The Eagles made one last run later in the half when they scored nine points in a row to make it 63-53.
But that would be as close as the Eagles would get as the Cardinals finished the game on a 21-10 burst. Eight Plattsburgh players scored in that stretch, with Manning getting six of the points.
Plattsburgh, unlike in some regular season games, didn’t allow Husson to go on a large enough run to get some confidence, even though Curle says there’s always room for improvement.
“I think our team does it intentionally just to give me more gray hair,” Curle said. “We throw long passes near the end of games with a lead when we should be working the clock.
“But you can’t make a thoroughbred into a trotter. It’s hard to slow us down. But we can get better.”
The Cardinals were able to play their final home game of the season in front of a near packed house.
