Stormers coach Allister Coetzee says that the team is suffering in Super Rugby as they have constantly make changes to the team due to injury.
The Stormers have now replaced the Cheetahs at the bottom of the Super Rugby standings following their 22-11 loss to the Waratahs at Newlands on Saturday, marking a sixth defeat in seven matches this season.
"We've had to change personnel week in and week out and many of the players coming in lack experience," Coetzee said after the game in Cape Town.
"Some of them are playing Super Rugby for the first time and have not yet played Currie Cup, we lack experience."
From the pre-season to the present, long-term injuries have struck hard in the Stormers camp and at various stages, no less than 11 players, including seven Springboks, were sidelined.
"What can you say, we are in a bit of a hole at the moment and it is just for this team to get out of that hole," said Coetzee.
"I guess we met the Waratahs at a bad time (because we are depleted) but there is a bye next week and it's a good time to re-look at our plans."
Coetzee explained that the lack of experience has, on occasion, resulted in poor decision-making during games. The outcome was that some players started losing confidence.
"When we get turnover ball, well, in our game plan-that's the ball we run, have a go, have a crack (at the opposition defence)," said Coetzee.
"There are decisions players make during matches which has been really strange to me. It's also strange, when we're in attacking positions we start kicking those balls away. It is a concern and that is why I question the confidence of certain players."
Stormers stand-in skipper Duane Vermeulen said despite the defeat he remained optimistic for the rest of the season.
"We had a good game plan and executed it well until half-time, but silly little errors during the second half proved our undoing," said Vermeulen.
"When you're on the back foot it's hard to keep your hands down at the ruck. Just the second half, we couldn't execute. There were slight errors, little small mistakes that crept in and that was our problem."
