The obvious conclusion being?The premise of the OP is flawed.
The selection committee are putting together a team, not selecting the 22 best individuals. Unless we know what the objectives are in selecting Suban (or any other "escaped goat"), we have no idea of if they are failing the objectives - but the doig is enlightening.
2015, Fyfe wins the Brownlow - by definition the best and fairest in the league, also got the players award (best player in the club according to Freo players). But only comes 4th in the Doig, behind Sandi, Mundy and SHill. The difference being, who was the best (eligible) player in the league vs who is filling the most objectives set for the player each game as judged by the coaches. It doesn't matter that he missed out on votes due to injury, in getting the Brownlow you'd expect that he would have received the maximum 5 votes so many times that it would put it beyond contention - and didn't.
The coaches are wrong.
