Souths were clearly the better team on the day and were well deserved winners.
Most things went Souths way during and before the game and most of the damage to the Dogs chances (injured players, match fitness, form, etc) was done before the game started.
Under the circumstances the Dogs did well just to make the GF and they did very well to be competitive and in touch on the score board deep into the game.
But at no stage did the Dogs lead or seriously look like winning.
To win they would have need a bit of luck and they would have need to put Souths under pressure but getting to a lead and Souths needing to score.
I am not sure any other team would have done much better, Souths were too good and it was only great defense and team spirit in the Dogs camp that kept them in touch.
Yes Souths probably got more of the 50/50 calls, but it is hard to argue that it changed the result.
In terms of the effort put in by both sides 20-6 is probably a truer reflection of the game.
But regardless, Souths were clearly the better team and their form in the semis was impressive, it is hard to argue otherwise.
