They conceded a late penalty for a defensive lineout, but on the whole their discipline and attention to detail was excellent. And that, as much as anything, was the key to their success.
"We've been there are thereabouts in most of our games this season, we just haven't been able to close out games," West, who swapped jerseys with Johnny Sexton afterwards, said.
"Being in a similar position tonight and being able to finish will probably give the boys a bit of confidence.
"All of us boys watched the 2005 [Lions] tour [to New Zealand] so it was something we were pretty excited about. We thought we had nothing to lose playing against a team like that."
Named on the reserves bench behind 19-year-old Stephen Perofeta, West has an uncertain future at the Blues. Otere Black, Beauden Barrett's back-up at the Hurricanes, is said to have agreed to join Umaga's men next season, and it remains to be seen whether West will stick it out in Auckland or perhaps move to Wellington as Black's replacement.
But whatever happens, nothing can take away his moment in the spotlight which helped secure a famous scalp, the first time a Super Rugby side has beaten the Lions.
One of the men confident West could go the whole way once he got the ball from 40m out was Rieko Ioane, excellent himself on the left wing, a player who scored the opening try and had two more disallowed.
Ioane was picking himself up on the halfway line when he saw West take Williams' offload, and said afterwards: "I soon as I saw him put the gas pedal down, [I thought] no one can stop that little fast fella."
