Is Steppie any faster than Meisiekind?

Wynand Olivier much pumped by some, is a decent enough player. He has a fine long pass, is quite physical and has the usual Bools inside step to the pack.  But he was always done in by pace. Giteau for example, tortured him through the outside gap....Wynand never had much top end, but crucially for a centre, he never had instant acceleration.

Then we have Stepfontein, much praised for a decent gap he took that helped seal the Boks win. That masked 70 minutes of frenetic but ineffective attacking play.

The question for me about Steppie is whether he has enough pace, or is doomed to be a Wynand type.  Two hundred and thirt y minutes against the ABs/Oz seemed to confirm that....does a break outside Horwill prove me wrong?

Frankly I'm not sure....but look at the try AC scored. He bumped shoulders with Step with them both running at the same pace towards the Bok line. He was Steppie's man to mark.....but by the time he scored Steppie was 5 metres in the rear view mirror. To me it looks like lack of acceleration and top end.
