Didnt Malthouse win at WCE?If you look at the total list of coaches who didn't win a flag at their first job, but did subsequently, it's not a big list.
Blight
Malthouse
Norm Smith
Robert Walls
Vic Belcher
And I think that's it.
On the other hand, 8 past premiership coaches have gone to another club and won a flag. Not a huge number, either.
