Two rounds of footy in the books and more and more is being learnt about the league. Whether it's fans, players, or teams as a whole, the AFL is offering up a lot to discuss.

1. Nobody understands the rushed behind rule

Is the rushed behind being phased out of AFL footy? It is one of the stranger and more unique parts to our game, purposely conceding a score to get a free possession of the ball.

On the weekend we saw a controversial free-kick given against Sydney youngster Callum Mills. He was judged to have rushed a behind without being under enough pressure not to warrant a free-kick. Liam Picken then snapped a goal for the Bulldogs at a crucial point of the game.

Since Friday night there has been much debate about whether it was the right call. What we have learnt from it all, is that no one really knows. Yes, he was inside the goal square, but was the pressure enough for it to be adjudicated as legal? The argument will rage on, and we still won't really know.

2.  Josh J. Kennedy will win the Coleman Medal

In round one he kicked seven straight, while this week he kicked 4.1. Kennedy didn't play his best game, he only managed nine disposals and five marks, yet to walk away with four goals is still a fantastic effort.

At the moment he only leads Jeremy Cameron by a goal, but he can still kick a decent bag without starring. Which would suggest that performances like his round one effort against the Roos will be common in 2017.

3. The Gold Coast Suns have hit a new low

The Suns are at the lowest point in their short history. Success wasn't expected early, however, in their seventh AFL season they are not as far along as they should be.

On the weekend they were destroyed by GWS, which just reminded everyone of the disparity between the two. The Giants are a year younger than the Suns, yet have already reached a preliminary final, and are premiership favourites for 2017.

Again they tried to top-up their list with experienced players such as Michael Barlow, and Pearce Hanley. Despite the quality of these players, this may only extend the Suns' run of relative mediocrity, with a complete list rebuild potentially in the cards.

4. The South Australians are on the march

The Crows and the Power are beginning to prove that they are genuine threats for the premiership. After great starts to the season, there was a focus and question of whether they would be able to back it up in round two. Adelaide beat powerhouses Hawthorn at the MCG by 24 points, and Port Adelaide destroyed Fremantle to the tune of 89 points.

Their play has been very convincing, and we get the opportunity to see them go head-to-head in round three. A South Australian side has not made the grand final since the Power were embarrassed by Geelong in 2007.

It is still very early days, but at this stage it does look like Adelaide and Port Adelaide, will play a part in finals footy.

5. AFL fans are still unsure about Essendon

They are 2-0 and are off to a dream start. However, the AFL community still doesn't know how to take Essendon. Some (mostly Bombers fans themselves) believe the players were wrongly done by, while others will argue that what they did was disgraceful. There are also many who are sick of hearing about the whole issue.

Thus, fans of the game as a whole are left with an interesting predicament, do they support the comeback story, or do they continue to hold their actions against them? This story will no doubt progress as the season does, so let's wait and see.
