Ryan Aldridge says he is not afraid to "change faces" at Basingstoke following Sunday's 8-1 home defeat to Belfast.
The Bison coach, 30, told the BBC he was furious with imports who strayed out of position during the defeat.
"We have to go through simple stuff 10-year-old kids are taught," he said. "Maybe they think coming over to England it's easier hockey. It's not.
"I'm not going to be on a team that loses. Either we change as a team or we change faces."
Fans have attacked a lethargic, passionless performance from the Bison against a vastly superior Giants outfit, and Aldridge admitted his short-benched team were too tired to compete.
"The guys are tired, we had a tough night in Coventry, and we've got two lines," he said.
"We changed our system to make it easier on some guys that haven't been able to adapt to the simple system we already play.
"That didn't suit me and they decided to play in other positions again. The guys were drained tonight but that's no excuse for being out of position."
Basingstoke, without a league win in seven attempts this season, travel to Cardiff on Wednesday with Aldridge ready to make changes.
"They'd better regroup quickly," he said. "It's not a holiday camp just because we're in Basingstoke. If the team continues to lose I'll bring someone in who's going to work hard."
Defenceman Kurt Reynolds, chosen as Bison man of the match, alluded to key players going missing as he spoke to the BBC.
"It doesn't help when you haven't got much support round the back. I'm sure everyone's going to be a little bit quiet in the dressing room," said the 23-year-old.
"We just need a few more goals to get a momentum up. We need to be prepared, no negative talk in the changing room, everyone's got to be positive."
Victorious Belfast coach and former Bison star Steve Thornton insisted Basingstoke would improve as the season progressed.
"The Bison were missing some key players tonight and it showed," he said.
"Ryan Aldridge is one of my great friends and it's tough because I know what they're going through in that locker room right now.
"You have to put it in perspective sometimes. If you don't have the bodies, it's tough."
Thornton praised his eight-goal heroes, adding that he believes Belfast have the squad to mount a serious title challenge.
"The team that has the most skill and speed generally wins it.
"You weather the storm of the teams who play tough, but we have the all-important depth. We can afford injuries to an extent and still pick up points."
