Not sure i’m convinced. I look at Martin at Richmond and Dangerfield at Geelong and reckon those two are the singular difference between those two teams being middle-of-the-pack plodders, and top 4. Geelong were actually middle-of-the-road plodders in 2015, then Dangerfield rocked in and put in back-to-back Brownlow seasons (even though he’s ineligible this year), and voila, top 4.
I think that has more to do with the peculiarities of the competition right now than anything else (i.e. no dominant teams and generally more even than it has been for 15-20 years), but i do think a player of Dangerfield’s ilk would be worth at least 3 wins to a mid-ranked team such as Hawthorn. Those 3 wins take you from 10-12, to 13-15, i.e. pretender to notional contender.
