Swindon Robins team manager Ronnie Russell says his side need to stop "throwing away points".
Russell's side lost 47-43 at home to Lakeside on Thursday, their ninth Elite League defeat of the season.
"This should have been the turning point, I felt it was an easy victory," he told BBC Wiltshire.
"I can't believe how many points were just thrown away. Points are hard enough to get but to throw them away that many times, it's so unnecessary."
He added: "You saw in heat 15, for a match that's already lost, you wouldn't see much more commitment. It was total and utter commitment from the boys. It's not like they don't want to do it."
Russell also questioned the fitness of Justin Sedgmen, who failed to get on the scoreboard: "Perhaps on reflection, he isn't fit enough.
"He might be fit enough to go to the gym but perhaps he's not fit enough to be back on his bike. The last thing I want to be doing is driving his confidence down.
"We have a three-week break now and in that three weeks he either has to get fit and start scoring points at Newport or we'll be looking to use a facility in that place."
