The Crimson suffered a difficult four game loss to NYU, 10-15, 15-11, 6-15, 8-15.
"The first two games were played well, but then we really started to play flat," Lewis said. "[NYU's] service picked up, and our passing started to break up."
"Saturday was such an awful game for us," Mager said. "We just really didn't play well."
After losing to Springfield on the road last Wednesday, the Crimson had hoped to toughen up its intensity for the road match against NYU.
"We just folded too easily during the match," said junior opposite hitter Josh Banerjee. "A lot of [why Harvard has lost six league matches] is purely mental. It's not because the teams are physically superior to us."
A season-long problem, Harvard's inability to receive tough serves, hurt the team throughout the match.
"[NYU] came out with a tough server, and that really put us in an early hole during the first game," Guilianelli said.
"We were a little complacent," he added. "We played them pretty close in the first game, and we thought that our momentum would be able to carry us through. But we really didn't have any defensive intensity, and our passing was pretty touch-and-go throughout the match."
The Crimson next faces MIT on Wednesday night at the Malkin Athletic Center. Harvard hopes to avenge a five game loss that it suffered at MIT's hands earlier this season.
"It would be really great to be able to get redemption against them," Mager said.
"If we play up to our potential, we really shouldn't face any problems winning against MIT," Banerjee said. --Senior Evan Mager
