They did something on one of the football shows recently - Talking Footy or Footy Classified, I can't remember which. But they put up a graphic showing Sam Mitchell's possessions in the GFs he's been in. 30+ possessions for the GFs, except for the 2013 Freo GF, the team that got closest to the Hawks in the past three GFs. Crowley held Mitchell to about 20 possessions with the implication being that to have a decent shot at beating the Hawks that nullifying Mitchell's influence was a decent strategy.
Personally, I think there's room for a tagger in this game. Crowley's spent a bruise-free year and I think still has plenty to offer.
