And Scotland will continue to play a wide game, he stressed.
It was a cracking good contest with something for everyone.
South Africa last savoured a win in Cardiff (24-15) during the 100 percent tour under Heyneke Meyer's charge in 2013, although of the XV that started that Test in green and gold, only Frans Malherbe, Eben Etzebeth (if passed fit), Francois Louw and Duane Vermeulen could see service again this Saturday; Siya Kolisi, Pieter-Steph du Toit and Willie le Roux were substitutes five years ago. Both teams displayed occasional brilliance when scoring tries in the first half although the match morphed into a tactical kicking contest after the break and the home side visibly exhausted in the final quarter.
It was Scotland's turn to apply some pressure but the decision to turn down the posts after 63 minutes and instead kick to the corner was one they would later regret, while Russell was fractionally off target with an ambitious long-range drop-goal attempt.
Following his travails against Wales it was nearly inevitable that Huw Jones should bounce back with an inspirational performance.
Wales have won their last three meetings with South Africa, but when the Springboks run out in Cardiff on Saturday, Warren Gatland's men will know they face a significant challenge. His cover tackle stopped Tommy Seymour in the second half, he scooped 18 individual points and his excellence only highlighted the inconsistent nature of his opposite number because Finn Russell had one of his up-and-down displays.
Erasmus is now in credit as South Africa's coach, with seven wins and six losses from 13 matches.
Pollard found a gap in Scotland's midfield before unloading to Embrose Papier, with the scrum-half using supporting forwards to make ground before finding Kriel.
Centre Huw Jones, his back to a defender, released winger Sean Maitland, took the return pass, and slipped the ball backdoor for midfield partner Pete Horne to score a wonderful try. Pollard spotted the mismatch in pace he had up against Ryan Wilson and was gone in a flash. The classy stand-off converted both tries and kicked a 24th-minute penalty only to see his half-back partner Papier miskick straight into the Edinburgh night sky and Laidlaw got the three back nearly immediately.
Four straight wins would represent a fine campaign, and the first time Wales have done so in the autumn - but an upwardly mobile South Africa side will have a different idea altogether.
He and Laidlaw traded penalties, and Scotland tied it at 17 when flanker Hamish Watson scored from a brilliant lineout move.
"Normally, the more inexperienced players you have, with less caps, you struggle away", said Erasmus.
A couple of Pollard penalties either side of a Laidlaw kick, however, saw the visitors nudge ahead as the game moved into the second period.
Laidlaw landed a 26th-minute penalty.
