Although a congested fixture schedule - Huddersfield are in action again on Friday against Blackpool - meant a full team was never in his mind, he believes there is value in the competition.
"It wasn't a brilliant spectacle I don't suppose. But this is a really good cup competition and an important one, make no mistake," he said.
"I wanted to go through, but needs must. It (the team selection) is no disrespect to the cup - it's a necessity.
"Our priority is staying in the Championship. We have two games in a very short space of time...we recover on Wednesday, prepare on Thursday and play again on Friday.
"I'm disappointed. I wanted to win and we might have won if we'd been at our best.
"But history tells me that this team was the right way to go, even with the risk of not qualifying for the next round."
