Despite dominating the game for 45 minutes, Town lost to three second half goals in Saturday's game at Carrow Road.
"We dominated the first half and didn't score, they dominated the second half and did - that sums the game up," the Town boss said after the 3-0 defeat.
"In the first half it was the Huddersfield Town that I like to see, apart from the ball not going in the back of the net, and in the second half it was the Huddersfield Town I don't like to see.
"To be so dominant for 45 minutes and then find yourself 2-0 down two minutes into the second half is absolute madness.
"We gave away two very poor goals to a good Norwich side and you can't afford to do that.
"It's very disappointing because we have now played very well away from home for two-and-a-half matches against Charlton, Leeds and Norwich and have got just one point to show from it."
