Your judgement of Butters quality is about as good as club's your list manager when they called Chayce Jones in 2018.I don't think he is a top 3 player in the comp, top 7-15 yes - but he has never stood up in finals so there is that. So I don't think he is worth more than a top 5 pick and a pick between 10-15 which is still a hefty price.
Ahead of him I'd personally rate at a pinch for their impact on games
Daicos
Bont
Hogan
Merrett
Cameron
Rankine
Cripps
D Moore
Neale
Heeney
Then you have guys like Jordan Dawson, NWM, Gulden etc
