Yeti, I think you are talking about Melbourne's 2nd goal. Melbourne's third goal was kicked by Bernie Vince which came from a stoppage where Barlow cleared it and got pinged for out of bounds intentionally.
Melbourne's second goal was kicked by Watts with about 8:18 left on the clock Q2.
From the centre bounce (with 8:46 on clock), Mundy was pinged for a throw, which clearly was a handball. Freo's clearance was brought back Garlett took the free, kicked it to Mitchie mark 55m out who sent it i50, loose ball get by Suban, Suban had space and time, looked upfield, had nobody, turned back towards Melbourne goals and handballed to Dawson who had 3 Melbourne players within 5m of him. Suban then pointed Dawson to go to Sheridan (who was behind Dawson). Dawson under pressure sent a soft handball to Sheridan who was contested by a bigger body, Hogan picked up loose ball, tackled by Dawson, Hogan got handball out to Watts who snapped from the boundary line under pressure for a goal.
From what I just saw in slow motion on replay, the umpire's dodgy free kick was the first thing to blame, then Suban, then Dawson, then Sheridan. Anyways, that's what the TV replay showed ... just saying.
