That is the opinion of Kieren Moss, their Australian winger who feels they could have won their last two games if they had done just that.
As it stands, Rovers are bottom of Super League despite a series of encouraging performances.
Moss, for instance, scored a hat-trick in Sunday’s Magic Weekend game with Hull FC only to still end up on the losing side.
Furthermore, they pushed Wigan – who have won their last eight games – close in the Challenge Cup less than a fortnight ago but eventually lost out after Danny Tickle’s red card.
“We showed we can tough it out with them and go right to the death with them,” said Moss.
“But unfortunately we had a man sent off as well and it happened on Sunday, too, with 12 men on the field (Nick Scruton being sin-binned versus Hull).
“We just can’t let those things happen any more. We’re shooting ourselves in the foot and we’ll have to do better.”
He is unlikely to play tonight, though, as fellow countryman Justin Carney hopes to be back from a shoulder injury that had sidelined him for the last three matches.
Moss, 24, had spent most of the season on dual-registration at York City Knights where he is League 1’s top-scorer and has 14 tries in just 10 appearances.
But the former Parramatta Eels player, who joined from Bradford Bulls 18 months ago, showed he can handle Super League with his recent performances against Hull and Wakefield Trinity.
On his time at York, where he could return, Moss said: “I just tried to stay positive.
“I just thought if I keep playing well and keep training an opportunity will open up.
“It was nice to get that hat-trick in the derby but they were tries any winger should finish. He’d be expected to do that.
“I just have to keep working hard to get a place here.”
