Gazing into the crystal ball that is the AFL ladder predictor, Andrew Wu and Peter Ryan deliver some final-eight forecasts that surprise even themselves on this week's tipping edition of the Real Footy podcast. Turning their attention to round 21, they pontificate over the prospects of the Western Bulldogs against GWS, weigh-up a fascinating clash between Adelaide and Hawthorn and disagree vehemently over who will triumph in Saturday night's MCG match between Collingwood and the Brisbane Lions.
