He wasn't the best player this year, plenty of players in front of him and far more influential. He won because there wasn't a single player with ability to consistently take votes off him.
Neale, Cripps, Bont and Danger (I can't believe I'm adding him) were leagues ahead of him this year in reality. His 2015 was incredible, but his 2019 wasn't anywhere near that. Mind you some of those 3 votes were actually laughable, in such thrashings too.
On another note Bont not polling high was insane, his 2019 was seriously Nat Fyfe of 2015...maybe better.
