No player beat more defenders across the championship than Steyn, the Glasgow Warriors captain’s tally of 26 seeing him top the standings following the five rounds of fixtures.
The winger also crossed for a brace of tries in the 50-40 victory over eventual champions, France, whilst claiming Player of the Match honours in the home wins over England and France.
Darge, meanwhile, led from the front in defence in Scotland colours, as the openside flanker finished with more tackles (74) than any other Scottish player across the championship.
His tally of eight turnovers was also more than any other player in the tournament, tying with Maro Itoje, Tadhg Beirne and Stuart McCloskey for the championship lead, whilst his display in the round three victory over Wales in Cardiff earned Darge the Player of the Match award.
