This is just insulting. You make it sound like Yarran is the most naturally talented player in the league and all he needs is to work hard and he'll win a Brownlow. There are plenty of players with a huge amount of talent that actually work hard as well, and are streets ahead of Yarran.
You think he'll consistently get 30-40 touches and carry a team on his back like Ablett? You think he'll be the top tackler in the league while also delivering truckloads of goal assists and goals like Jack? He'll be an even more damaging clearance player than Dangerfield, O'Meara and Pendlebury? He'll turn games off his own boot as a forward in a horrible team like Cameron? He'll have more impact around the middle than Naitanui? This is what you're saying when you make the utterly insulting claim that he will win a Brownlow - that he would be better than all of these super talented players.
