See now youre making shit up, no he wasnt, watch it again. Youre talking about the mark to Hoskin-Elliott in third right? I'll explain it to you because youre obviously very emotional right now. Cox was running to the goal square but was being blocked/ held up (not a free mind you) by Hooker. Cox still trying to move forward still being held (it is not a free, im not saying it was - good defensive positioning by CH) but then he moves sideways as WHE sees the opportunity to use Cox and create seperation from his defender for the lead. I'll say it again, good forward craft and that is all, no holding, no coralling. Watch it, and not just the end bit with the replay, watch the leadup.
If you going to nit pick each umpire decision youre in for a long day. Go to work, take youre mind off it, read a book or something, walk the dog and relax. Maybe I should bring up the Baguley decision in the last quarter, free kick there? yah right. It was garbage both ways.
