Certainly this is going to set the coaching merry go round in motion. A few clubs will be looking at Nathan Buckley, and Richmond's going to have the first opportunity to conduct formal talks with him. If Collingwood's serious about getting him then they're going to have to move quickly.
Worsfold's safe. They love him over there. In a few years West Coast will be back up the ladder. There's quite a bit of talent there, they're just too young to be all that competitive this year.
Harvey, on the other hand, is in some trouble. If they finish bottom 4 again this year (which is likely), I'm not sure if he'll be there next year. Neither will Pavlich, I don't think.
