Dusty is astounding. Can't comment on Jack Dyer, but I do think KB probably shades him at the moment with 5 flags and great performances in finals. I think you would need to put Dusty on a par with Royce Hart.
To say this is elite company is an understatement.
He has the time to reach Bartlett and also Bartlett played over 400 games so comparing on the basis of opportunity, given Bartlett had more opportunity playing for so long, Dusty can very easily be rated as on par. If Martin continues like this then I reckon he will go past Bartlett.
Very different players but both could turn a game, we are so lucky to have had both play for us.
