Observations

A-League

There haven't been many surprising results over the Christmas/New Year period. The thing that is really of note is that Sydney FC are 48 points clear of the team ranked second by Elo ratings - Melbourne Victory. Four teams now have a greater than 95% chance to finish in the top 6, and Wellington is looking strong for a 6th place finish. Of course, given Sydney's huge ratings difference it is little surprise that they are a 98% chance to play in the Grand Final. Perth's win over Sydney on the weekend meant their predicted chance of finishing top 2 jumped from 39% to 63%, and are now predicted to finish in 2nd place, ahead of  Melbourne Victory. 

BBL

At the time of writing this the Brisbane Heat are the only team with a positive rating gain in the last 7 days. The Heat have only an 8% chance to make the top 4, but a lot can change very quickly in BBL. The Perth Scorchers are still a very strong chance (86%) to make top 4, which is largely due to the number of home games they have remaining all of which they are predicted to win.

NBL

The New Zealand Breakers (+20) and the Taipans (+17) are the big movers over the last 7 days. Both teams had big upset victories, but it hasn't changed their chances of playing finals (both are predicted to finish outside the top 4). The top 3 spots look to be locked up, so the battle is now between Perth and Brisbane, with New Zealand and outside chance to make up the 4.
