Big Boy Jack Darling has gone missing in big games. Or more notably, big moments in Grand Finals. Two decisive dropped marks in 2015 and 2018. Granted he stepped up at home to Richmond last year but that was a home game, and did the same again against Collingwood in the qualifying final. One good quarter in the 3rd of the 2018 GF isn't enough for me. He wasn't cited in the first half, and ghosted again in the last.
Probably more proof they are the big 4, Richmond are a toothless tiger without these 4 at their best or unavailable. The other players who seemed good players go back to being very average without these 4 in the side.
