I think the championship is Perth's to lose.
Townsville are not going to make finals.
Wollongong will miss out
The top 4 is now 5 teams fighting for 3 spots, with Perth likely to get the MP. Adelaide could steal it, but need Perth to drop a few easy ones for it to happen.
Cairns - Need to win 5/7 games, probably 6/7 to make it happen, They have beaten Perth twice, so if they did finish 4th Perth should panic slightly. Likely to finish out of the placings.
NZ -A run of "easy" games for them and with the split on Sydney likely, they need to win 6/9 games to make finals. 3/9 games against Cairns so still very much open to 4th spot. They are +14 on the split with the Tigers too so their season is very much alive.
Sydney have the split on the Tigers, so watch out there. To finish 3rd they need Melbourne to drop a few easy ones and hope to finish on even wins. If they finished 3rd, then the Sixers might need to redraw some plays. Likely to finish 4th or 5th.
Melbourne - really only have 1 easy game out of 7 left which means they could be well hardened come finals. Likely to stave off and hold onto 3rd, but could tumble to 5th if they only win 2 or 3 of those 7.
Adelaide - The toughest run home - 95% sure they will make finals, but ladder position could vary.
Perth - Have made finals, should finish top, but only an entree of complacency will ensure they tumble off their perch.
Come finals, Adelaide have as good a chance as any of the 5 teams. I would say the probability of winning the flag at this point of time is:
Perth: 60%
Adelaide: 30%
Sydney: 5%
Melbourne: 4%
NZ: 1%
Betting wise, I would drop money on Perth, a lazy $20 on NZB as the smokey, and a bit on Adelaide.
