From the beginning of the year, we've said Limerick could win another All-Ireland, so long as they don't beat themselves. Here they are, middle of December, and the same caveat applies.
It's hard to see the match-ups where Waterford can be confident of winning. That's a problem for Waterford – and it's a problem for Limerick.
Waterford have to respond to that tactically and Limerick need to deal with it psychologically.
If they're careless and Waterford get a couple of goals, that's like spinach to Popeye or a cape to Clark Kent.
Waterford are honest and continuing a theme of performance and development that took a dip after the 2017 All-Ireland final, without ever being broken.
Unfortunately for them, having added a lot of additional cheer to this short, happy season, Limerick's level of performance looks stronger and more enduring.
Liam Cahill was fond of goals as a player and is fond of goals as a coach, but other than a goalscoring display from Waterford, akin to their two previous wins in '48 and '59, it's only cockiness or complacency that will snap this Limerick run.

The undercard on a fantastic feast of hurling is provided by Antrim and Kerry in the Joe McDonagh Cup final.
Two former Tipperary goalkeeping greats will be on either sideline, with Darren Gleeson guiding Antrim and Brendan Cummins steering Kerry.
The two teams face off against each other for the fourth time this season, with the Saffrons victorious in all three of the previous encounters.
Kerry still have a number of players from the 2015 Division 1B promotion/relegation play-off where they shocked Antrim.
Antrim have injury concerns around the fitness of their talisman Neil McManus, but have more attacking aces in the likes of Ciaran Clark and Conor McCann.
Even in a time of high-scoring rates in hurling, their 14 goals in four games to date is very impressive.
A victory for Kerry would not be as surprising as in 2015, but I expect the attacking firepower of Antrim to win through.
