Interesting question: if you had to decide who had the better season between B Hill so far this year, or D Pearce (the bloke he might have squeezed out of the team) last year, it would be a no-brainer right?
Statistically they are very similar.
Clicky
I reckon B Hill helps stretch the defence, which wouldn't be captured by stats, but he is statistically a worse kick (in both efficiency and clangers) and only tackles half as much. Interestingly D Pearce averaged more clearances from 50 and inside 50s than B Hill, which would suggest D Pearce also got on his bike. B Hill hits the scoreboard a little more though.
B Hill also possesses D Pearce's rare skill of demonstrating in the same game that he is capable of doing the impossible and incapable of doing the simple.
