And neither is a given.
After this evening's game, the Blues will take to the road for four of their remaining five games, three of those against neigbours, the other over in Galway which means nothing's guaranteed bar perhaps bonus points.
But then again, their Round 21 game at home to Benetton Treviso, is a racing certainty five pointer for the boyos in blue. Factor in that five and their game in hand and all of a sudden, the gap separating them from top spot could basically comes down to tonight's encounter at the Cardiff City Stadium.
That's how good this competition is.
Maybe thats why England (Inc.) should be thankful they snatched a RBS Six Nations title after a stuttering campaign where their Rose breasted best eventually, and some might claim, inevitably, were forced to play second fiddle (off key) to an Ireland Magners League, honed and hungry Ireland side.
Tonight though is a huge game. It's one Munster will not want to lose. It's one Cardiff Blues simply cannot afford to lose.
