Collingwood has already been active this trade and free agency period, snaring Daniel Wells and Chris Mayne via free agency, while Brisbane captain Tom Rockliff is also rumoured to be in the Pies’ sights.
Damian Barrett reports that both players have been offered to at least one club as trade bait.
However, it would appear to be a strange decision from Collingwood, given the pair only recently arrived at the club.

Aish was recruited by the Pies just last year and played 15 games this season, after two year with the Lions, while Greenwood crossed to Collingwood in 2014 after seven seasons and 74 games with North Melbourne.
