WATCH: Read's dreadful act of poor sportsmanship
Crockett's infringement was cynical enough, but the most heinous act of grubbery was left to the All Blacks captain Kieran Read.
With Crockett in the bin and with Scotland playing with the benefit of advantage, watch as Read clearly slaps the ball forward out of the hands of Jonny Gray from the deck.
The ref somehow misses it despite it happening two metres from him.
Advantage should have run and Read should have been binned after for a professional foul on his own line, leaving New Zealand with 13 men for the final nine minutes.
New Zealand eventually won the game 22-17.
