Jim McGuinness has not been back in the hotseat long but he appears to have transformed Donegal into All-Ireland SFC contenders already.
It had been a lean decade for the county after McGuinness - who famously guided them to the Sam Maguire Cup in 2012 - first departed with the last couple of years of his absence particularly trying.
Expectations were low for Donegal going into the 2024 Ulster Championship given their recent struggles, but McGuinness sparked something in the team that presumably few else could.
Their dramatic defeat of Armagh in winning the title showed a rediscovered resolve under McGuinness, having beaten favourite Derry en route to the crown.
Their comfortable defeat of Tyrone on Saturday was their best in years, winning by seven points in Ballybofety.
Legends like Michael Murphy have called time on their careers but a new-breed has bred fresh optimism, in tandem with the results on the field.

Sean Cavanagh claims Jim McGuinness' new Donegal can be better than his old side
Tyrone legend Sean Cavanagh - who knows all about playing against McGuinness' Donegal - has high expectations for Donegal after what he has seen from them this season.
Writing in his column for The Irish Mirror - which you can read in full here - Cavanagh has claimed that Dublin and Kerry will be keen to avoid them in the race for the Sam Maguire.
He also made a bold prediction that McGuinness can take them to even greater heights than in the past.
"There isn't a team in the Championship that wants to play Donegal. Why would they? Saturday was further evidence that they are a nightmare to play against.
"Suffocating you in defence, giving up very few goal chances. A goalkeeper whose kick-outs are lethal weapons with a midfield capable of dominating that sector.
"They don't have massive players like Murphy, Colm McFadden, Neil McGee and Karl Lacey from his first Donegal team.
"But, to me, I think this team is shaping up to be a stronger unit. They may well end up being better than the side that won the 2012 All-Ireland."
A big claim from Cavanagh considering the heights McGuinness brought his first team to over a decade a go.
One thing is for sure, it is a good time to be a Donegal supporter.
