But you are missing the point that improvement can come from players already on the list, you don't necessarily have to bring in an established player from another club to fill a position from leaving players. Not everyone is a superstar in their first year as an 18 year old. Caddy out means more midfield time for blokes like Menegola, Lang, Cockatoo and GHS. Trying to state as fact that 'because player XYZ has left and no player of equivalent talent was brought in means you are going to be worse off' isn't correct, because the opportunity it opens up for others could lead to improvement. Or it might not.
I dont disagree with that. But Geelong are dealing with exactly the same issues Hawthorn are dealing with. For every bit of improvement in a young player, there is a falling away by a senior player.
Hodge/Burgoyne/Gibson and Lonegon/Mackie/Taylor are all on the wrong side of 30 and Mitchell/Lewis and Bartel/Enright are gone. For every bit the respective teams young players might improve these guys are likely to get worse or are not there at all.
