Incident assessed:
Contact between Geelong Cats’ Mitch Duncan and North Melbourne’s Aaron Hall from the second quarter of Sunday’s match between Geelong and North Melbourne was assessed. The ball is handballed to player Hall at half forward for North Melbourne who prepares to kick for goal. Player Duncan, who is positioned in front of Hall, runs quickly towards him and leaps in the air in an attempt to touch or smother the ball. While in the air, Duncan turns his body and his momentum carries him into Hall making high contact with his back. It was determined by the MRO that the action was not unreasonable in the circumstances. No further action was taken.
Firstly, I don't think this was a suspendable incident
With that out of the way and noting the bolded bit above, I detest how the governing bodies (MRO, League Admin, Umpires) make decisions based on what they think a particular player is thinking at that time. Deliberate out of bounds the obvious example. We're blessed to be governed by so many individuals skilled in the art of mind reading
