I guess we also have Ed as a last resort option? Let's hope he's not needed, howeverThat's the big risk on the table for sure. However I don't think things will change much - match winners in key positions are a rare commodity and take more time to develop etc etc ...not so easily replaceable.
Finals and finals wins and genuine sustainable contention - will see Carlton being able to draw a developed player or two ( if not a match winning type) in areas of need going forward - that is the other factor in how much you have to pay and who might be interested.
eg Cameron to Geelong was a huge coup - same as Buddy to Sydney - despite the 'cost' you do a deal like that without blinking.
I would have like Ollie wines a couple of years ago (or Oliver which was loser than many understand) or Tarranto this year to add proven class to the midfield. William's faux move to midfield duties not woking out ( so far?) was a big disappointment to me.
I'm a tad concerned about Hewett and Kennedy's injuries - we need Carroll/Cuningham/Kemp to come on...
