Zorko, Kennedy, Couch or Kerridge?

[Hazza09]

Hi guys

Which one of the 4 is worth getting?
I need to activate my midfield link with my forward line.
I know Zorko is injured but I'm not sure on the others.

Midfield is: GAJ, Murphy, Watson, Selwood, Coniglio, Shiel (Magner, ______)

Kennedy the others arent certain to get named round 1 and then you would have missed the boat on Kennedy.
