The death of Down football has been greatly exaggerated. The Mourne men backed up last week's impressive win over Meath win an even more emphatic victory at Celtic Park.
Eamon Burns' side were full value for their eight-point win over a disappointing home side.
Down's forwards enjoyed a field day, with Darragh O'Hanlon, Ryan Johnston and Barry O'Hagan all on song.
Down blitzed Derry early on, surging into a 1-10 to no score lead.
Johnston's goal on 20 minutes typified everything that was good about Down.
An early ball fizzed into the livewire Barry O'Hagan; he fed the on-running Johnston, who ran on and drilled the ball past Thomas Mallon.
Derry flickered brightly just before half-time with Emmett McGuckin bagging a goal, but Down were home and hosed at 1-11 to 1-3 up at the break.
Two O'Hanlon frees extended the Down lead soon after the restart as the men in black and red bolted the door on their opponents.
Down's sizeable lead was always enough to ward off any thoughts Derry may have harboured for a fightback in the second half, as the Mourne men ran out comfortable winners.
They face Kildare next with promotion very much now in their sights.
