Essendon coach Kevin Sheedy ushers me into the grimy sanctuary, suggesting his star break his silence concerning the racial slur uttered against him in the dying minutes of a pulsating drawn match, abuse drowned out by the roar of almost 95,000 fans at the AFL's inaugural Anzac Day contest meant to commemorate mateship.

In the immediate aftermath of the match against Collingwood, Long maintained the players' code of silence. Days later in the gym he still refuses to avert his gaze.

Confiding to my television crew from the ABC's 7.30 Report that we will either secure an exclusive interview or Michael Long will end up with biceps the size of Arnold Schwarzenegger's, I asked them to set up in Essendon's trophy room and wait.

Long reluctantly concedes to discuss the controversy. His initial on-camera responses prove as evasive as his on-field sidesteps. 

After 20 minutes he has revealed little. Frustrated, I ask him to set aside everyone else's commentary and bluntly put the critical question: "What does it mean to you to be called 'a black bastard?'."

"It's degrading a person for not only who they are but for their colour as well," Long responds.

Then he gives an answer carrying the burden of history and the power of a universal truth: "We're just the same, we bleed the same. But people have an opinion on people they don't know. They don't care what colour their dog is, or their car, but when it comes to people it's a different issue. Why should it be? Why can't we live together as one?"

Long uttered these words 20 years ago. Speaking up changed AFL culture against on-field abuse. Dual Brownlow medallist Adam Goodes called out crowd abuse. Hopefully this will end abuse from beyond the boundary. 

It may also lead to greater understanding of the history of Australia's black-white relations. The past is never dead, as William Faulkner noted, it's not even past. The mothers of Michael Long and Adam Goodes belong to the stolen generations, taken from their families as children. 

A learning and leadership centre named in Long's honour recently opened in Darwin to help uncover the successors to football stars such as Long and Cyril Rioli.  

The AFL, Essendon and Collingwood football clubs will add their clout to the summit because footy has played an important role in social progress. It should not be diminished by flashpoint controversies.

The last time Long visited the learning centre in Broadmeadows, encouraging children to further their educations, he could barely stand because of his football injuries. He thanked me for the loan of a couch. I thanked him for an Essendon premiership and his knee. The Long Walk continues. Slowly. Courageously.
