The Bears' big win over Wests put the undefeated premiers six points clear of the Lions after two home and away rounds.

Every season the Claytons Cup is awarded to the best side in Country NSW and generally requires an undefeated run to the premiership, as the Bears did in 2014, after winning their first Cup in 1951.

Since that 2014 grand final win over Gunnedah, the Bears have only been beaten twice, both at home against traditional rivals Wests in 2015, who went on to take the minor premiership, before Norths beat them in both the major semi-final and then grand final to take back to back titles.

This season the Bears have never looked like losing, their closest contest a 14-6 win in the mud at Narrabri, and this Sunday the Bears will face the Blues again.

Narrabri have looked good on paper all season but have only just been able to put it together in the last few rounds, banking wins over Wests and Gunnedah, although were outplayed by fellow improvers Oxley Diggers in between those wins.

The Diggers are still three points behind the fourth-placed Narrabri although, after stringing two wins together, still have a mathematical shot at their maiden finals series as they host Gunnedah this weekend.

Captain-coach Tim Coombes said that after the Diggers took the Bulldogs to golden point last time, and with two wins in a row under their belt, the side would be heading in with plenty of confidence.

"We are definitely improving as a club," Coombes said. "It was golden point last time and this time we are at home and have some momentum.

"The boys know that they can compete and that is all we have to do."

The skipper has been laying the platform from the front row alongside Sam Schiffman, although the past few weeks he has been more impressed with what his halves and hooker have been doing with the ball.

Firebrand hooker Micah Scarth might have come under some scrutiny from Coombes after being sent off and binned a few times recently, although a few weeks of better composure has coincided with the two victories and the skipper believes that is no accident.

"There is a good feeling in the club at the moment," Coombes said.

"We have settled down, improved our discipline and aren't playing frustrated footy."

"Micah is quick and is now as good as any in the comp."

Outside Scarth, the halves combination of veteran Tim Walsh and young halfback Scott Berry has also been firing.

"Tim takes a lot of pressure off Scotty in there.

"They have been very good the last few weeks."

A win this week would put the Diggers right in the mix and would be a record fourth for the season.

"Gunnedah is the game for us," Coombes said. "If we are any chance we have to win this game."

The other match will see the Lions return to Armidale.
