I wish I could be as confident about SD's performance as you are. He appears to have learned nothing from his train wreck at San Siro last year, where he continually allowed the Italian front row to lift, twist, bore in and drop the scrum, and then penalised Tialata for being unable to cope with the illegalities that his opponent was being allowed to commit with impunity.
His scrum management in the Stormers match was just a carbon copy of that match.
Much as I dislike the idea of a hometown referee, I would rather have seen Joubert in charge of this match. He is undoubtedly the best referee in SANZAR, and his scrum management is second to none world-wide (with the possible exception of Alain Rolland).
