Did complacency undermine Mayo?
Who would have seen it coming - Tipperary footballers beating Cork, Galway unseating Mayo and Cavan forcing Tyrone into a replay with a late goal?
That leaves Leinster as the only province where the odds, so far at least, are running true to form. And, with Dublin's giant thumb pressing down on the province, it's hard to see much change any time soon.
Mayo's defeat has changed the overall championship dynamic. They were expected to win Connacht, which would have taken them in the same direction as the Ulster champions but now they could pop up anywhere.
That's assuming, of course, that they remain sound on the qualifier route.
You would have to wonder if their flop against Galway was down to over-confidence.
Galway gave their best Connacht SFC performance since 2008 but would still have been surprised at how listless Mayo were after Thomas Flynn's goal.
Mayo had been swamped with tales of how Galway would be easy prey and irrespective of how often manager Stephen Rochford (left) preached caution, complacency may have infiltrated the camp.
Still, all is certainly not lost for Mayo. Galway (2001), Tyrone (2008), Kerry (2009) and Cork (2010) won All-Ireland titles from the Round 2 qualifiers, proving that if a team is good enough, the route doesn't really matter.
Of course, here's the question: have Mayo the required resilience?
