The team total of 82 was the most by a team since the Roosters beat Canterbury 87-7 in 1935. Sam Walker has starred for the Roosters in their 70-point thrashing of the Cowboys in Townsville. The Cowboys are hanging on in eighth position but will drop back to ninth if Canterbury beat Melbourne away on Friday night. Roosters captain Tedesco, fresh from a hat-trick of tries last week, started and finished the opening try and it was carnage from that moment.
