As much as I'd like to see Slattery rubbed out for plenty of weeks to somewhat help even up the competition, the only thing he did wrong is slightly get off the ground when he bumped. Maybe 1-2 weeks for poor execution of the bump, but didn't think it was that bad. Unlucky for the Sturt player to break his jaw.
Not sure how you would call it 'unlucky'. Slattery charged in from a good run up, was always going to hurt Stephens. Until the last few steps Stephens had his back to Slattery, had he maintained that stance then it would still be an illegal hit. The only way it could be legal was if Stephens had turned side on after he had hand passed, seen Slattery and braced for contact. 6 weeks and I can't see how you could argue for less.
