I'm not so sure that the "bottom 4 is sealed". Norf, Weagles & Tigers are all a lock for the bottom 3 positions. Adelaide & St Kilda will definitely finish 14th & 15th, but the order in which they finish is anyone's guess.Thank goodness for another Swans loss. Only have themselves to blame for poor goalkicking (4 rushed behinds too). I reckon they are starting to feel the pressure now and that is a good wakeup call for them. Premiership wide open and could be won by several teams (Carlton, Sydney, Brisbane, Geelong, Pies, Freo and even Essendon and perhaps the Giants or Port). Gold Coast are done, St Kilda won't be playing finals but are giving it their best and Hawthorn's % is probably too low. Bulldogs and Demons too inconsistent. The bottom 4 is sealed. After a slow start to the season the Lions have taken full advantage of a recent favourable draw and if they finish top 4 they are a chance for sure.
If you'd said that the "bottom 5 is sealed", then I'd agree with you.
