"Our minds were in a good position but the bodies let a few of us down," Clever said. "It was tough with that short turnaround."
Given that the Americans notched just their third win in six tournaments, they were not about to quibble with how it was achieved. Coach Eddie O'Sullivan, never afraid of hyperbole, described the performance of his players over the previous 160 minutes as "extraordinary".
If you were unkind, you would say there wasn't a lot of quality to Russia's play. There was plenty of willing, but an absence of sophistication and cunning. The scrum started poorly, which was better than the lineout.
The scrum improved - both sides said they could not hear the referee's commands because of crowd noise in the first half - but the lineout didn't.
"If we won our ball in the lineouts, we could have won the game," said Russia coach Nikolay Nerush.
A significant problem was their "hands falling off", but we can assume that got lost in translation.
At times, the USA looked so dominant you feared a rout, but there was never any quit in the Russians. They made most of their tackles and piled numbers into the breakdown, which made it difficult for the USA to find rhythm.
Russia did have the honour of scoring first, before USA fullback Chris Wyles evened things up from 40m.
Then came the game's only real moment of fluidity, with the Suniula brothers, Roland and Andrew, combining to put hard-working halfback Mike Petri in near the sticks.
It then took until the 65th minute for Wyles to push the USA beyond the seven-point buffer - hardly edge-of-your-seat stuff, but then again, we've seen far stronger teams show less enterprise during the first seven days of this tournament.
Given the conditions and the minnow status of both sides, a decent crowd turned out, including a few notables.
No match thus far has been able to compete with the Eagle versus Bear for star-pulling power. Russian Deputy Prime Minister Alexander Zhukov arrived in New Plymouth on Wednesday and was yesterday joined by billionaire vodka baron Roustam Tariko and Miss Russia, Natalia Gantimurova.
Prime Minister John Key hosted Zhukov in the luxury suite at Stadium Taranaki before Vladimir Putin's confidant jetted out immediately after the game.
USA 13 (Mike Petri try; Chris Wyles 2 pen con)
