Sydney Roosters captain Boyd Cordner believes "freakish" fullback James Tedesco has achieved greatness this season and statistics support his case.

Already the Roosters' player of the year in their 2018 premiership, Tedesco is enjoying the best season of his career in their title defence.

After the completion of the regular season last weekend, Tedesco topped the NRL in three major categories – tackle busts (124), line breaks (25) and average running metres (187).

A favourite for the Dally M, Tedesco will also enter the finals with the most tries and most try involvements of all fullbacks and his numbers show an increase on last season across most key categories.
