The most damning statistic was that Swansea City did not have one shot on target, even after Andy Carroll's ludicrous red card with half an hour left. It will lead to the usual criticisms, that Swansea are soft, that they pass the ball too much and could do with a bit more thrust and, whisper it, some good old-fashioned British blood and thunder.
Yet their plight is more nuanced than that. It is not necessarily the case that Michael Laudrup's side could do with a Plan B, more that they have misplaced their A-game and forgotten what made them successful in the first place.
After losing Carroll, West Ham retreated and ended the match with three centre-backs on the pitch, but Swansea played into their hands by dumping cross after cross into the box. While it might have looked like an alarming betrayal of their ethos, it also suggested they have lost confidence in themselves; the snappy, incisive passing that has earned Swansea so many plaudits was nowhere to be seen.
Swansea badly miss Michu, who could return from injury for the visit of Cardiff City on Saturday, and are sleepwalking towards the bottom three. They have won one of their past 10 league matches and this defeat left them two points above 18th-placed West Ham.
Although Laudrup said that he still believes in Swansea's style, he certainly compromised at Upton Park by selecting Jordi Amat as a defensive midfield shield in order to combat the aerial threat of Carroll and Kevin Nolan. It did not work, though, Carroll creating both of Nolan's goals with cushioned headers from high balls into the box and it meant that there was no place for Leon Britton. Swansea's diminutive midfield orchestrator, the player who sculpts so many of their attacks, never made it off the bench.
"It's not nice," Ashley Williams, Swansea's captain, said. "I don't enjoy it, to be honest. It hurts. It's embarrassing. It's on the TV. We lost again. We lost too many games, too many goals conceded. It does my head in. I'm as frustrated as anyone because we're all responsible. It's the time to look at the table. But it's not nice viewing for us. It's the first time it's been like that since I've been at Swansea, I think. It's not nice."
What also wasn't nice was the way the preposterous Chico Flores got Carroll sent off, flopping to the floor as if he had been felled by a right hook from Manny Pacquiao, when in reality the top of his head had been brushed by a flailing arm. It did not even look intentional but Howard Webb fell for it and Carroll will miss West Ham's next three games if he does not win an appeal against the decision.
Despite that disappointment, West Ham's 10 men were never in danger and showed no signs of fatigue after Wednesday's 0-0 draw at Chelsea. Digging in after having a player sent off has become a feature of Sam Allardyce's time at Upton Park.
"It's all about everybody knowing they have to work a little bit harder and then focus on one major thing, which is not letting the opposition get too many chances," Allardyce said.
"Don't open yourself up too much. And defend in the final third with your life. That's why we've got 11 clean sheets this year, our defending is superb. So just a few more goals and we'll be out of trouble, no problem."
Now there's a man who is never short on confidence. Swansea could take a leaf out of Allardyce's book.
