Manhattan (3-4-1) was unable to recover.
"They're a tough team," first-year Manhattan head coach Brett Nelson said about West. "They don't have any weak links and work really hard off the ball-it's just one of those things."
Nelson said the lopsided final isn't a true representation of the Indians.
"Our kids did a good job-they played well," Nelson said. "The only thing we learn is to work that hard off the ball. Talent wise, (Blue Valley West) is not that much better than us. It's just the way they work as a team and how hard they work off the ball.
"At some point we need to learn that."
Nelson said he was also happy with his team's never-say-die attitude, especially in a game that was so out of hand.
"Jordan Donohoue, Kelsy Schoen and Madison Joyce worked their tails off," he said. "They never gave up and kept working and working.
"Those are signs of good players and of a good team when they don't give up — they played tough."
The Indians return to action on Thursday when they host Topeka High at 6:15 p.m. at Anneberg Park.
