ANGRY Jon Sharp has admitted the Giants let themselves down badly as they slumped to a 17-10 home defeat to Hull KR.
The loss leaves the Giants rooted to the foot of the Super League table.
But while Huddersfield earned praise in defeat for their opening two displays at home to St Helens and at Bradford Bulls, the sad reversal against promoted Hull KR is a different matter.
The Robins are the bookies' favourites for relegation and were huge underdogs against the Giants.
However, the visitors produced a superb first-half showing to open up a 16-0 lead after 33 minutes and then defended magnificently when the Giants took firm second-half control.
An inability to take their chances ultimately cost Huddersfield the win, and Sharp was unable to contain his anger at a flurry of mistakes.
"I'm extremely disappointed," he said. "I felt we let ourselves down from a discipline point of view, and this was a big step back for us.
"I thought we looked a little bit loose and gave Hull KR some opportunities which relieved the pressure.
"At no stage did we build pressure.
"In that second half, we created a great many chances and then blew them with poor execution. There were times when we should have taken the tackle rather than looked for the pass.
"We have to make sure we learn from this as quickly as possible and smarten up our act for the next match (at Leeds on Sunday, March 4).
"We knew exactly what to expect from Hull KR, it's just we didn't react to it.
"They were full of enthusiasm and looked like a typical promoted team, working hard for each other.
"While their completion rate in the opening hour was 100%, ours was around the 45% mark and we were already firmly on the back foot.
"We did make a fist of it late on, but we left ourselves too much to do."
Sharp was today checking on the fitness of his players, but it seems they all came through unscathed.
There is no game next weekend in any case as St Helens (their scheduled opponents) play Brisbane in the World Club Challenge at Bolton on Friday.
