It meant Cooper was reviled by many on these shores during the 2011 World Cup. He was booed every time his face went up on the big screen and heckled when he touched the ball.
McCaw and All Blacks coach Steve Hansen even asked fans to move on from their hatred of Cooper but it wasn't that easy.
After all, as McCaw wrote in his book published last year: "The intent of what he was trying to do [when he kneed McCaw in the face] pissed me off more than the execution. Shortly after that happened, I was carrying and should have passed, but I lit up and I saw Quade standing in front of me and clattered into him instead.
"I was disappointed in myself doing that," he added, "letting it get personal. There's no need - players like Quade get sorted. Sooner or later they get their beans."
Perhaps it was karma, but Cooper suffered a serious knee injury early in the third and fourth place playoff against Wales in the 2011 World Cup at Eden Park. As he was helped from the field in obvious pain, it was about the only time the booing stopped.
Cooper has been less relevant to New Zealand fans since then because he's never really been the same player.
Veteran writer Spiro Zavos described Cooper as "the 'Picasso of the Pass,' with dazzling speed of hand" but who also has "a dark side to this genius". "In tough situations for his team he disappeared from the battle."
There has also been the controversial moments alongside his inconsistent form and injuries. He was in conflict with the Australian Rugby Union over the size of his contract and was left out of for the 2013 Lions tour after tweeting in 2012 that the Wallabies' environment was "toxic" under Robbie Deans. He considered a switch to rugby league, with the Eels reportedly offering him $1.5 million over three years, dabbled in boxing, fighting on the undercards of his friends and stable-mates Sonny Bill Williams and Anthony Mundine, and last year joined French club Toulon.
He was very good at times but in January, Cooper and former All Black Ma'a Nonu were criticised by Toulon owner Mourad Boudjellal, who said switching from former England first-five Jonny Wilkinson to Cooper was like "going from foie gras to pate".
Cooper is expected to start at second five-eighths for Australia in Wellington on Saturday but it's more circumstances than form with Matt Giteau, Christian Lealiifano and Matt Toomua all out.
He's still a polarising figure and some may boo him because that's what people have always done.
"He's brought it on himself but probably it would be good if we all got over it," Hansen said in 2013.
Cooper will be ready for any manner of reception. A trawl through his Twitter account reveals a philosophical side.
"Good days give you happiness & bad days give you experience," he said, borrowing a line used by basketballer Michael Jordan. "Both are essential."
