The maul goes no where, other than spinning around some. Hooper's breakout takes everyone by surprise. The scots react far more quickly. They have to turn and chase. While Higgers and Hunt are giving up 2-3m to them, they are already on the front foot.
Kuridrani chases also but runs an outside line which I presume is unseen by Hooper. Nabuli does the same but further out. Neither of them really feature at all in the sequence despite being in a reasonable position. Dhp and Folau aren't seen again in the sequence.
I thought the one of Scots detached from the maul to chase, but by luck he had come off the maul a second earlier, but is behind Hooper and only just in front of Higgers. In any event, the scots end up with 9 players swarming onto Hooper, all of whom are closer than the first wallaby support player (Higgers).
One is the scot fullback who makes the tackle. Two are their wingers, who probably had head starts on their AUS counterparts and really only serve to corral Hooper to the fullback.
Two are scot front rows. One of whom came from behind Hooper at the maul and one who came from the blindside of the maul. The other four scots are from their defensive line (last feet) and are a mixture of forward and backs.
Higgers is our best chaser, but even he is too slow to react, too slow running and then completely ineffective in his attempt to clean out the ruck. Easy to pick on him, but the other support players were more ineffective.
