Guilderland caught a break later in the second quarter when it recovered a CBA turnover deep in the Brothers' territory. Barcomb connected with Andrew Smith on a 20-yard touchdown pass, and Kevin Forbes added a two-point conversion run to put the Dutchmen ahead 8-7.
Guilderland was going to start the third quarter with the ball, but a fumble on the kickoff return fell into CBA's hands inside the Dutchmen's 10-yard line. Guilderland's defense tightened, though, and forced the Brothers to turn the ball over on downs after Weaver failed to stretch far enough for the first down at the 1.
The Dutchmen couldn't turn the defensive stand into a sustainable drive, but a long punt by Nick Zanotta pushed CBA back to its half of the field. The Brothers didn't threaten to score again until Weaver picked off Barcomb and ran the ball back well into Guilderland territory.
"There was a miscommunication on the pass route, and that was why the interception happened," said Penna.
CBA out-gained Guilderland 168-92, but nearly one-third of the Brothers' yards came on Chaires' long touchdown run in the second quarter.
"Their defense was equally tough," said Smith. "Their inside linebackers were tough to get through."
"We just misfired at times at every position. We just couldn't get any continuity going," said Penna.
CBA advances to Friday's class AA semifinal game against top-seeded Ballston Spa, while Guilderland closes its season with a crossover game against Shenendehowa.
The Brothers figure to be an underdog against Ballston Spa, which has won six consecutive games, but Weaver said his team is ready for the challenge.
"I think we're underrated. We have some good athletes," he said.
Meanwhile, Guilderland will try to beat Shen for the first time since 1995 and wrap up its most successful season in a decade with a victory.
"We had our shot, and we were unable to capitalize," said Penna. "I have to look forward to playing Shen, and I think the kids are excited to play against a quality opponent.""
