There's hardly any ex-players who've left Freo and then criticised the club in the press.
There does seems to be a respect, grudging or otherwise, for the club that helped to develop them.
In turn, I'm always pleased to see an ex-Docker - like Crozier - who didn't quite make it as a first team regular here, for whatever reason, go onto become successful at another club.
Booing these blokes when they return"home" is just wrong. They ought to be warmly welcomed back, like old mates who've left town for better opportunities.
Unless their new team wins, of course.
On the other hand, booing umpires should be mandatory.
