Newcastle prop Kade Snowden has rued disappointing errors and an inability to contain Manly halfback Daly Cherry-Evans following a hard-working display in his side's 30-10 loss to the Sea Eagles.
The Knights made 12 errors for a 69 per cent completion rate in their loss to the Sea Eagles who completed at 81 per cent.
"We start good every week then we just make those stupid mistakes," Snowden said.
"We back them up two in a row and that's what hurts us and that's what allows them to put points on us."
As the only specialist prop named in Rick Stone's final 17 to face the Sea Eagles, Snowden had to pick up his output in the middle of the field, running 17 times for 129 metres, while making five offloads and 32 tackles.
"It's the same every week," Snowden said, "that's what you've got to do when you're a forward, that's your job."
The Knights hard man also refused to blame a lack of size up front for his side's defeat, insisting the powerful backrowers his coach named were up to the task.
"We've got a few players who can play prop, David Fa'alogo and Korbin Sims [are examples]," he said.
The front row wasn't the only area of the Knights team under pressure on Sunday afternoon, with Jarrod Mullen's injury forcing a reshuffle that saw Dane Gagai play at the back with mixed results.
"I think he played really good, he only trained a couple of days in that position so for what he did out there and for how long he trained for that position he did really well," Snowden said.
Knights coach Rick Stone agreed, praising Gagai's ability to spark the attack.
"I thought he was real good actually, he made a couple of little errors but overall for his first game at fullback he was good," Stone said.
"Sione [Mata'utia] hasn't been really comfortable at fullback... he's an 18-year-old fella and he's still got a bit to learn in the NRL."
