Lol id rather murph than steven. Billings would be perfect.None of these are very fair comparisons though, as they are all positionally different players.
Cripps is a better inside player than Ross, who's still a good player. Steven is a better outside midfielder than anyone we have currently, though Curnow is a better key forward than any on St Kilda's list. Docherty is a better half-back than any for St Kilda as well. That being said we don't have a small or mid-sized player as good as Billings or Gresham.
