Huddersfield caretaker coach Chris Thorman said he lost his rag with his players at the break in their defeat to Castleford.
The Giants were 28-6 down at half time, with their only try coming from Tonga forward Ukuma Ta’ai, while the Tigers scored five in the first half.
Huddersfield came produced a fightback in the second half, but it wasn’t enough as Casteford ran-out 40-28 winners at the John Smith’s Stadium on Sunday.
Speaking after the game, Thorman said: “I went ballistic at half time.
“I said to them that I know they’re capable and I know with the injury there’s plenty of excuses thrown around, but I know the blokes that started and finished can beat teams and do their jobs.
“It shouldn’t take me to lose my rag and get personal with plenty of them to get a response. I asked them why it takes that and they couldn’t answer it.
“I’ve got a fair assessment of why I need to do that and hopefully I’ll see some improvement in some of that.”
Thorman believes the Giants have enough talent to pick up wins, but says their enthusiasm needs to improve.
He added: “It’s really disappointing that it takes me to lose my rag to give them some energy and enthusiasm for them to go and have a crack.
“The reason we got back into the game was because of energy and enthusiasm with a little bit of game plan, we saw some good execution and I was really happy with Innes (Senior) finishing his try.
“There are fine margins at this level and we needed to chance our arm a little more. I just needed my ball players to take the initiative and grab the game by the neck.
“I thought if we completed two or three sets when we tried to chance our arm a little bit too much then I honestly thought the result could have even gone the other way.”
Huddersfield welcome Salford Red Devils to the John Smith’s Stadium on Sunday, 3pm kick-off.
