Donegal easily overcame Derry by 2-13 to 0-9 to set up an Ulster SFC semi-final meeting with Tyrone.
With 10 points to spare at the end of another confident attacking display, Donegal have shaken off the critics who lambasted their defensive strategy last season.
The Tir Chonaill system has moved on, evolved into a confident counter-attacking game to which Derry had no answer.
An added bonus from this Ulster SFC triumph was the return of Michael Murphy, who made a low-key comeback with three points from frees, and they will look forward to a semi-final clash with Tyrone with some confidence.
Donegal's massed defence frustrated Derry, and Leo McLoone's 30th minute goal helped them to a 1-6 to 0-4 interval lead.
Colm McFadden netted a second goal, and the Oak Leaf response never materialised, with nine different Donegal players getting their names on the scoresheet.
Paddy McBrearty was denied a third goal by the woodwork late on.
