Fifteen rounds in and the AFL 2008 season looks a race in three.

Geelong are clearly the team to beat displaying ominous form over the past few weeks and sending a shiver down the spines of all challengers.

The Bulldogs and Hawthorn have shaped up as the two main contenders for the Cats, and the three have shot clear on top of the ladder.

The only possible other finals challengers appear to be Collingwood and Sydney who have both shown strong form in patches.

The rest of the competition at this stage are merely making up the numbers and won't challenge come September.
