"It was a couple of soft tries. If we'd kicked some of the points that were available to be in with a chance, but we didn't deserve to be.
"Midfield defence, we were caught out a couple of times.
"We were unorganised in the backline but that was to be expected. Between Josh [Hamilton], Rhema [Sagote] and Tevita [Taufu'i], they haven't spent a lot of time together."
Wanganui lost lock Sam Madams to the sin bin six minutes before halftime for dragging a maul down inside Wanganui's 22m.
A South Canterbury player also got a yellow late in the game, as Wanganui did rally in the second half to score tries through hooker Cole Baldwin, winger Jaye Flaws and reserve lock Lasa Ulukuta, as they had the better of the final 25 minutes.
However, they had left themselves too much to do.
Hamilton was able to add only a penalty, while South Canterbury's goal kicking centre Paula Fifta, who came to that province from Tonga last year, filled the role of the departed Liam Edwards with a 16-point haul from a try, penalty, and all four conversions. Fellow backs Jared Trevathan, Erenimo Tua and Kurt Rooney scored the other five-pointers.
On the plus side, Caskey was happy with how the lineout combination functioned with Baldwin throwing in for Madams and Sonny Woodmass, as Wanganui won the majority of their possession and stole a couple off South Canterbury.
It was also a relief that unlike 2013, there were no major injuries to report after the opening game, with all players expected to be available for selection for the first home match against Horowhenua-Kapiti this coming weekend.
First on Caskey's mind will be trying to pull an honest 80-minute effort out of squad, as while the opening weekend of the competition provided a couple of surprise results, winning right from the start of the campaign is mandatory if hopes of a return to the Meads Cup playoffs are to be realised.
"It doesn't make life easy at all."
