Kettering produced a second-half demolition job on Coalville as they ran out 70-16 winners in Midlands One East.
An error-strewn performance in the first period saw them go in 16-13 down and drew a sharp dressing down from the coaching staff at the break.
The Blues responded in fine style as they ran in 57 unanswered points.
Joe Daniel had scored all the first-half points but he went into overdrive during the second period.
He got three more tries, seven conversions and a penalty for a personal haul of 45 points.
The other scores came from Jamie Manley, Josh Plowright, James Taylor, Steve Fraher and Andy Byrne.
In the cups, Rushden & Higham benefited from Kesteven pulling out of the Intermediate Cup while the reverse was the case for Oundle who withdrew from the Junior Vase.
In the Senior Vase, Stewarts & Lloyds maintained their superb start to the season by knocking out Sleaford.
They put in an excellent display on their travels to win 56-14 in Lincolnshire.
There was not so much good news for their neighbours Corby although they came within a whisker of winning their first match of the campaign.
It needed extra-time before they finally succumbed to Keyworth in the Junior Vase.
It was 15-15 at the break and 20-20 at full-time meaning an added period was needed.
It proved too much for Corby whose valiant effort ended with a 37-20 reverse.
Steven Moore, John Forbes (2) and new signing Joe Lavaunau got their tries.
And manager Ricky Egan was philosophical in defeat.
“I can’t complain at the result today, we were outfought in the forwards,” he said.
“However, at this club we have a set of backs that are a match for anything this league has to offer.
“We only need to work on the forwards, as soon as they are firing and setting up a platform for the backs we are going to be some outfit.
“It’s a pity that the game was a cup match as at full-time we would have walked away with two points for the draw and a bonus point for tries.”
