The Dragons looked set to warm up for Friday's RaboDirect PRO12 against Treviso in the worst fashion against London Welsh on Sunday, trailing 14-9 heading into the final quarter.
However in a Steffan Jones-inspired turnaround Edwards' side scored 33 unanswered points, the fly-half contributing a club record 27, to run out 42-14 winners.
After five consecutive defeats, Sunday's win was the Dragons' second on the spin in the LV= Cup and while it was not enough to secure qualification to the semi-finals it certainly put Edwards in a positive mood.
"The first half was pretty static and boring," Edwards said. "It was like a game of chess but I'm extremely pleased with our second-half performance.
"We have some talented individuals who began to express themselves. Their try spurred us on and it was important going back into the RaboDirect PRO12 next weekend that we finished with confidence and momentum.
"He's (Steffan Jones) a point-scoring machine and he and centre Jack Dixon, with his off-loading today, were particularly impressive."
