Why would he? By that time he’d be an 8 year Melbourne player, he’d have his own personal friends at the club, He’s already a finals player, and creating his own legacy at Melbourne. He’d be well and truly entrenched at Melbourne by then which he probably is right now, he wouldn’t give up on he’s doing at Melbourne because his grandad played at another club 60 years ago.
Players don’t leave clubs to play for their childhood team they supported. They really only leave for go home reasons or better opportunities.
Strangely despite his name, he was actually never a Collingwood supporter - instead he supported Richmond.
