Brawl breaks out between Port Adelaide and Geelong
The first quarter between Port Adelaide and Geelong culminated in a mass brawl that refused to simmer down way after the siren had sounded.
Port Adelaide resorted to playing almost "dirty" football to solve their woes, but ultimately got cleaned up by Geelong at Adelaide Oval on Saturday night.
The match review panel is set to issue a lot of fines to players from both sides following an ugly, near all-in melee at quarter-time, started when Port's Tom Jonas charged into Patrick Dangerfield and rekindled when the Power's Jasper Pittard knocked over third-game player Tom Ruggles.
The AFL is also likely to investigate a heated exchange between Geelong coach Chris Scott and Port's Hamish Hartlett as the teams went to their huddle at quarter-time.
And it was after these off-the-ball spates of anger that  the Power lost control. Port led by four goals at quarter-time, but Geelong then punished them by kicking nine of the next 10 goals, again leaving the Power in disarray, at times as if they lacked unity.
The match was televised live on China Central Television and the Chinese would have even choked on their rice when Port looked the better side early only to have a meltdown in discipline and allow Geelong to seize control.
Full credit to Port for their early vastly improved intensity; their hard tackling and relentless attack on the ball, but ultimately Geelong exposed their weakness – not enough quality players who can execute skills and have impact to change the tide of the game when Geelong gained momentum, starting with two vital goals by Dangerfield late in the second term.
This was far from a classic win; the Cats simply ground their opposition into oblivion and made it 13 wins from their past 15 clashes, including the record-breaking 2007 grand final.
Joel Selwood exemplified the Anzac spirit. His leadership was inspiration, his courage unquestionable as per normal, and his workrate was astonishing.
However, this win was also largely about a terrific team effort. Port, under pressure given their record-loss to GWS Â the previous week, were always going to go in harder, and for Geelong to weather the ugly stuff early was great work.
Dangerfield probably copped more attention, especially early, from Port than he probably will when he confronts his former club Adelaide for the first time, at the Adelaide Oval in round eight. Overall, he played well given the circumstances.
Mitch Duncan was brilliant midfield, Corey Enright resilient in defence and Tom Hawkins and Steven Motlop caused Port headaches in the forward lines. Also pleasing was the most effective game by Daniel Menzel, who after going into the game kicking 1.7 in two games, bagged goals to put this result well beyond doubt.
It was the same across the board. Geelong didn't start well, but Port's rising inefficiencies – and the tenacity of the Cats – allowed them as a team and players  to work into good form.
No one should question Port's workrate, but their execution under pressure was ordinary. The good news was that Darcy Byrne-Jones, a 20-year-old playing his third game, again showed a lot of poise in the backlines and appears to have a long future in this game.
Charlie Dixon contested extremely well, and deserved to kick goals. Unfortunately for him, his teammates didn't deliver enough quality inside-50 entries to give him more chances.
But when Port desperately needed their higher-profile players like Robbie Gray, Chad Wingard, Justin Westhoff and Hartlett to set the example in that disastrous second-quarter they weren't to be found. And it won't be only the Chinese left to ponder how a side could kick five goals in the first quarter and struggle to kick another over the next three quarters.
