Skipper John Smit left for the World Cup under siege to hold his place in the Springboks team yet he will be creating new records when he leads the defending champions against minnows Namibia on Thursday. Local writers caustically rated Smit as far from the republic's best hooker after an underwhelming international season and coach Peter de Villiers was under pressure to ditch him. But Smit, 33, will lead out the Springboks in his record 109th appearance, in his 15th RWC match and a world record 82nd time as Boks skipper against the 19th-ranked Namibians at North Harbour as De Villiers continues to stand by his captain. "I think our biggest challenge is to manage our players. We had two really bruising encounters, and from all of those John Smit is the only one standing, so you can see how valuable he is," De Villiers said. Smit will take the field for his third consecutive tournament Test while keeping Bismarck du Plessis on the replacements bench as the Springboks look to back up their 49-3 dispatching of Fiji last Saturday. "It is a good stepping stone to where we needed to go and to improve from last week. A lot of guys put some valuable time out there and some guys really put their hands up," Smit said. "We were aware that we came into the tournament pretty undercooked from a rugby game time point of view so it was important for us to progress." Du Plessis cannot mask his frustrations sitting on the bench: "Show me a player content to sit on the bench and I will show you a liar," he told a South African newspaper. South Africa have won their last nine RWC matches and are expected to equal their record of 10, a run that started in 1995 and was ended by Australia in 1999. The Boks have only lost one of their RWC pool matches -- against England 25-6 in 2003 -- and in their only encounter with their African neighbours swamped them 105-13 in Cape Town four years ago. The comparison is stark. The Springboks are two-time World Cup champions, while Namibia have yet to win a single RWC match and were hammered 49-25 by Fiji and 49-12 by Samoa at this tournament. "I really believe in my team and we can give South Africa a good show," Namibia skipper Jacques Burger said. "You've got to believe you can compete against them and you've got to believe you can beat them even though the odds are against you a lot of the time. You've got to be up for it every time. "We've got to keep the ball as much as possible. A team like South Africa, if you give them a lot of ball, they're going to score a lot of points against you. That's just the way they play." If, as expected, the Springboks cash in with the points former IRB world player of the year and winger Bryan Habana could become the all-time Springbok record tryscorer, an achievement he currently shares with Joost van der Westhuizen on 38 tries. Habana is among five Springbok changes with Gio Aplon on the other wing, Francois Hougaard to start at scrumhalf with Fourie du Preez on the bench, while flanker Willem Alberts replaces Heinrich Brussow and prop CJ van der Linde gets his first start of the tournament at tighthead. Locks Victor Matfield and Johann Muller, centre Jean de Villiers and flyhalf Butch James were not considered for the match. "There is no way that we will fall into any sort of comfort zone. The competitiveness between the players is just too strong and the pride to give your best for your country and the Springboks is too big," Hougaard said.
