Could not disagree with you more. It's utter nonsense.
The football department and the football department alone should be the arbiter of who to retain and who to let go. Nothing is more so when the player involved is 34 years old and showing signs of slowing down. Junior's long spell out after incurring a hamstring injury was an indication of this. Over at Collingwood, they won a flag after dropping experienced players like Fraser, Lockyer, Medhurst and ultimately there was no sentiment left even for Neon Leon. Ask any Magpie fan and they'll tell you that those decisions made the difference between winning a flag and missing out yet another time.
We're entering a new era and you might not like it but there's no place for sentiment and if Cam Bruce was spooked by Junior being told to go at 34 or if he made some emotional decision to leave because he was unsure of his position at the club then IMO the decision to stand firm was not only totally vindicated but stands as proof that, for the first time in almost five decades, we as a club mean business.
