The Crusaders won the last of their seven championships in 2008, but while they may be powerhouse of the competition, during the Super 14 era the Bulls ruled at the expence of the red and blacks.
Each of the Bulls titles came with a Crusaders scalp, but this knockout match's time around it will not be Pretoria or Soweto (that normally gives the Bulls a massive advantage), but the cosy confines of the new AMI Stadium.
The Crusaders have never lost a Super Rugby Finals Series semi-final on home soil, and McCaw said personally he might owe the Bulls a result or two.
"I probably owe them one," he said.
"We've had some tough old battles over the years, but this is a new year."
While the Crusaders are almost unbeatable at home, McCaw said that the mindset had to be correct.
"You still have to do the job right and you can't go out thinking that it is going to be easier," he said.
McCaw will play at number eight after Kieran Read had been ruled out, but it wasn't a fellow flanker that the All Blacks captain pinpointed as a threat, but the boot of Springboks sniper Morne Steyn.
"The experience we've had over the last few years is that he keeps things ticking along just through our ill discipline," McCaw said.
"Anywhere in your own half and it is fairly much three points guaranteed."
"They're not real subtle how they approach it, they try and get on top physically and they can kick the ball from anywhere."
