What has Judd done that has benefited Carlton so much ? You have away Kennedy one of the best KPF in the game now & also gave away a top 3 pick. He moved you up from from the bottom but all that did was rob you of another early draft pick you would have been better of receiving in 2008.... Carlton has never made it past the semi Finals in Judd's 7 years in the navy Blue.
You are confusing trade with player here when considering the question asked. Which makes no sense unless wanting to muddy the view of a clear perspective on what a player brings to the table.
You don't recognise what Judd did for WCE? I ask how long have you been watching football? You ask what did Judd do for Carlton? I ask again, long have you been watching football? What Judd did with both of these teams, one being the centre piece of the best midfield of the day that went B2B GF's for one flag before moving to a perennial wooden spooner team and lifting them up to a kick of a Preliminary final; is pretty obvious for anyone paying close enough attention. Hodge would not have had anywhere near the impact Judd had with either of these sides. Not a hope in hell.
