Just looking up his history, he's coached a team in his own right (Claremont in 1999 and 2000), served on the WC board from 2001 thru 2004, was a highly regarded assistant to Neil Craig at the Crows in 2005 and 2006 before going back to Perth for business/family reasons. He's been responsible for "strategy, stoppages, and structure" at West Coast in 2014 and 2015.

There's a lot of good stuff in that CV whichever way you look at it. Success seems to follow him.
Very interesting that current head of football David Noble was also an assistant at the Crows during Pyke's time at the club and obviously he's a former premiership team mate of Worsfold's.
