A big part of that evening session was putting pressure on the player's fitness and then getting them to do their set-piece drills when the tongues were hanging out.
Caskey wanted to see more of a push forward - like the occasions when a player joins the ruck, he expends the extra energy to get to the place where the team is short, rather than just piling into the breakdown at the first opening he reaches.
This was about showing more urgency to help each other out, the coach said. 'It was pretty basic, really. We weren't there at the start of the [South Canterbury] game. "When people are tired and under pressure, they might take the easy option."
Horowhenua-Kapiti came back from 14-6 down at half-time to tie Thames Valley 19-19 in Levin last weekend, and while Caskey is trying to get some footage from that game, it would not arrive until later today at the earliest.
What is clear is Wanganui must be the superior at man-on-man defence, as last year in Levin it was clear the forwards were dominating in the tight five, but Horowhenua-Kapiti had backs capable of thriving in broken play.
Fullback Michael Tambour is back for more, while Wellington import and former top amateur golfer Perry Hayman could be a threat, being one of around seven import and origin players in the wider squad.
"They'll definitely be pretty dangerous out wide, so we'll make sure we work hard out there." said Caskey.
There will also be an interesting brother vs brother clash as Wanganui lock Sonny Woodmass will again face his sibling and fellow NZ Army representative Tainui Woodmass in the pack.
In the curtain raisers, the Wanganui Under 19 team will play Horowhenua-Kapiti at 11am, then the Wanganui Development team will begin their Rugby Development Officers (RDO) Shield campaign against Wellington Maori Colts at 12.30pm. Kick-off for the Heartland match is 2.30pm.
