MacDonald fully expects their play-off fixture to reach a similar climax.
"What a game of rugby it's going to be," he told media. "If the last two games are anything to go by, there will be a bit of drama and a cliff hanger.
"It's just about delivering now, and getting out there and doing the job. We didn't do it at the weekend, we're well aware of that."
MacDonald was referring to the final-round 31-22 loss to the Hurricanes in Wellington, which left his team second in the overall standings.
Losing their perfect record in the competition didn't concern the former All Blacks fullback.
Of more concern was their lack of precision and discipline at crucial moments, two qualities that had been a hallmark of their 14-from-14 start to the season.
"We threw a lot at them, but we definitely weren't accurate enough and gave away too many penalties when we had them under pressure, and gave them easy outs," MacDonald said.
"If you put teams under pressure, you have to keep them under pressure - you can't let them off the hook. It just shows how important discipline is in everything."
Both teams will be named tomorrow, with the Crusaders expected to be at full strength.
Their All Blacks starting front row, rested against the Hurricanes, should be re-instated, while influential second-five Ryan Crotty should be back from the hamstring injury suffered early in the first test against the British & Irish Lions.
