Quite a few people feel that Yze will be needed less as we now have Maric & Aussie.
It is rare that several first year players have a significant impact in the same team. Whilst there are outstanding efforts ala Davey, Selwood, etc they are the exception rather than the rule.
The other thing to remember is that Aussie is not even on our senior list yet and won't be until when have a long term injury.
