Our list is filled with players who do one thing brilliantly and everything else poorly: Warnock and tap work, Robinson/Bell and bullocking, Curnow and tagging, Casboult and contested marks, etc etc.
Only 1 of those (Warnock) cost us a pick in the first 2 rounds - 3 were rookies.
If you want to point the finger in the past decade then Kennedy, Grigg and Hampson are at other clubs, Bower fizzled out, Bootsma is no longer at the club, while Lucas and Watson can't get a game.
