Province retained their unbeaten record after six games of the competition and now travels to Durban to take on the second-placed Sharks on Saturday. Coetzee's team had to work hard to stay on top of the log, relying heavily on the kicking boot of flyhalf Willem de Waal.
The pivot scored all the points via 5 penalties, but the coach afterwards said he was very pleased with the team's performance and the win. "I am very pleased with the 4 points.
"In the past we would have lost close games like this, but this performance shows the young side we got is maturing and has matured. The way the squeezed out the win today was good. It was as tough a Currie Cup game as you will get.
"Matthew Proudfoot (forwards coach) mentioned during the week that it will be test match rugby and it was exactly that, so I am very pleased with the win."
It was not only the WP senior team that put one over their opponents, but the under-19s and 21s also beat their counterparts from the Blue Bulls. Coetzee said Province supporters should be glad about the fact that things are starting to fall into place now in terms of the structures at WP.
"To get 12 points against the Blue Bulls on a day is a good day at the office. Our youth policy where we want youngsters coming through is paying off in the form of Nick Koster, who started today.
"He played very well against a helluva physical Bulls pack. Tim Whitehead is also back in the mix after the loss of our Boks and he did well. Then there still is Lionel Cronje. Our youth policy works well and it says a lot for the systems that are in place.
"These are not things that happen in a year, it happens over a number of years."
Explaining WP's decision to go for position rather than posts on four occasions in the first half, captain Anton van Zyl said he felt they had the momentum and upper hand at that stage. He said with hindsight they should maybe have gone for the points.
"It was always 20-20, but I felt we had the upper hand at that stage and wanted to follow it through. Instead of being a bit chipped for not taking the penalties we should rather look at the reasons why we were not accurate enough to take 7 points.
"We would have felt more comfortable to be on the back foot in the second half with a 9-point buffer rather than a 6-point one, but then again we could have scored two tries and then we could have thought about a bonus point."
Coetzee said he supported his captain 100% in his decision-making. "Like he said, we played a lot of rugby in the beginning. We were dominating in the first couple of minutes. It was a 50-50 call and we have a policy in case of a 50-50 call when you have the squeeze on the opposition you go for broke.
"Hindsight is an exact science, but I am happy with the way he handled the decisions."
Coetzee added that they will be disappointed with the overall performance given the high standards they have set for themselves. "But in the context of this game, when you look at how many Springboks were missing form both sides and the pressure of playing in front of a capacity crowd at Newlands, I think the game produced top class rugby.
"It was top class Currie Cup rugby, but we would have to go back and see why we had white-line fever. We had opportunities and we didn't take it."
