We're rebuilding too, in fact you could mount a case that says pretty much any side out of the current top 4 is rebuilding. So what makes Collingwood so special? Of our 5 best players today in an 105 point away smashing, the oldest player was potential AA Jacobs at 26.
Same with WC. With Cox and Glass retiring this year Priddis is our oldest player on our list at 29. With Butler and Waters probably retiring very soon (due to injuries both are depth) our next oldest players on our list are 27.
Its quite possible starting next year the top 5 ages on our list are going to be 29,27,27,26,26
