In regards to the PSD I guess a lot of that depends on how keen Richmond and Carlton are to sign a 29 year old ruck whose done a knee and is intent on coming to the Dogs on a 3 year deal. Obviously, it wouldn't be a sure thing, but a risk that I'd be prepared to take if the Crows try to do something ridiculous (such as a McMahon + Tiller package for example that was suggested in todays Advertiser, BAH!).
As far as trading Tiller, I agree that I'd be reluctant to do it too - I have genuinely liked what I have seen of him so far, and I think he has an excellent platform as far as his shape to certainly develop into a key forward. I guess a lot of it depends on if we get another forward somewhere else during trade week or whatever.
I certainly wouldn't want to be trading McMahon, Gia or a 2nd Rounder for Hudson, as has been suggested in this thread.
