At the end of this season, I would be letting go of Stanton, Howlett, Hocking, Bird, McKernan, Brown, & younger blokes like Long & Morgan & I reckon Jobe & Kelly will retire - so there's 10 blokes already, almost 25% of the list gone. That seems enough of a turnover for one year, so in a sense I agree with your logic, just disagree on Myers only.
Well I have only watched 3 VFL games this year & have been underwhelmed by our younger AFL listed blokes to say the least. The only one showing any consistency is Mutch & he is a classic wingman, so unless Colyer gets injured, we won't be replacing like-for-like, plus he will do SFA to help our centre clearances.
The most conspicuous players I've seen in the VFL are either the older blokes like Bird, Howlett & Hocking, or the VFL listed blokes like Ferry, Boyse & Hind (be interested in DJR's thoughts on that).
So if you want to reward mediocrity with gifting undeserving players in the 1sts, well bully for you, but I prefer players to earn games while we are still a chance to play finals. Once finals are out of the equation, I have no issues with gifting games for the last 2-4 rounds.
