Other than...
Running the most meters of any front rower on the ground in the grand final - 2nd most for any forward only just behind Katoa who made a line break on the edge and played 80, Willison only played 40.
Most post contact meters of anyone on the field with zero errors or penalties conceded and a grand total of 1 missed tackle.
Averages 111 meters a game with most of that off the bench.
95.6 tackle efficiency.
Covers Prop AND Second Row at an NRL standard.
Was great for us in both games against the 'Riff and in the Grand Final.
Doing that on the biggest stage, and representing Cook Islands and New Zealand (Maori All Stars and the NZ squad for the current tournament).
If representing your country, wearing a premiership ring and having impressive stats in the Prelim and GF is "hasnt proven much yet" - then you're a hard person to impress.
The kid's one of the most in demand young forwards in the game, we were all crowing when he re-signed.
