Clive Griffiths wants his side to “man up” in attack in order to get over the National One finish line.
Knights’ title hopes suffered a setback with defeat at promotion rivals Rosslyn Park last weekend - but the Castle Park club remain in control of their own destiny.
Doncaster will return to the Championship if they win their three remaining fixtures against Wharfedale, Coventry and Blackheath.
But Griffiths says his players must be more clinical with the ball if the long-time leaders are to finish off the job.
“We dropped the ball too much and there were too many forward passes and bad passes,” said Griffiths, reflecting on the 21-18 defeat at Park.
“We only completed 29 per cent in attack, compared to 90 per cent in defence. Eleven times we didn’t get the ball from a set piece.
“The defence manned up and put their bodies on the line.
“But if we’re going to win the title we need to be more accurate. We can’t afford to cough up that much ball.”
Griffiths remains bullish about his side’s tough looking trio of remaining games, which starts on Saturday against a Wharfedale outfit that got the better of Doncaster earlier in the season.
“We’ve dusted ourselves down,” said Griffiths. “Now let’s go and express ourselves.
“The defeat at their place still rankles with the boys and that’ll be an extra motivating factor this weekend.
“We’ve still got a cushion at the top,” he added.
“Rosslyn Park know they have got to get 15 points out of 15. They’ve got to throw the ball about and win their games handsomely.
“We’ve got to get 12 points - three wins. We know what we need to do. It’s still in our hands.
“It would’ve been nice to have won at Rosslyn and had the chance to finish it off in front of our own fans this weekend.
“But it wasn’t meant to be. We’ve got to do it the hard way, but we’re still confident we can finish the job.
“We bounced back from our last defeat at Fylde by winning the next seven. Now we have to emulate that and win the last three.”
