|Pat Tillman, who was killed in Afghanistan after turning down a multi-million dollar contract in the NFL and is now lionised due to his sacrifice, was a growing critic of the war [GALLO/GETTY]
Howard Cosell said that "rule Number 1 of the sports jockocracy" was that sports and politics didn't mix.
And yet last night, at the ballpark in Philadelphia, we received another reminder that some political expression is deemed not just acceptable but glorious.
When the killing of Osama bin Laden reached the Philadelphia Phillies fans, amidst their 14-inning loss to the New York Mets, boisterous chants of "U-S-A" filled the park.
This was praised across the sports landscape as a remarkable, yet altogether appropriate moment of national joy.
"It was beautiful," said one radio commentator. "It reminded all of us what is so wonderful about sports in our society."
The eruption of patriotic emotion at the park should surprise no one.
Since 9/11, the sports arena has been an organiser of patriotism, a recruiter for the US armed forces, and at times a funhouse mirror, reflecting the principles of freedom in a manner so misshapen and distorted as to rise to the level of farce.
As the Phillies faithful cheered, I thought about the NFL postponing games following 9/11, but only after a players revolt led by Vinny Testaverde made clear to Paul Tagliabue that no one was in a condition to play a game.
I thought about the spread of Military Appreciation Nights at the stadium and the increased prevalence of jet flyovers and troops processions in the field.
I thought about the military recruitment stations organised outside preseason NFL games.
I thought about Major League Baseball adding the second national anthem, "God Bless America" to the 7th inning stretch.
I thought about the late Yankee owner George Steinbrenner having chains put up along the side of the bleachers and hiring off-duty police to make sure no one did anything but pay fealty to the flag.
I thought about a young man named Bradley Campeau-Laurion who was led from the park in handcuffs because he left his seat to use the bathroom during this celebration of freedom.
I thought about ESPN's week of SportsCenter from Iraq in September of 2004, which allowed the network to do what George W. Bush couldn't: connect Iraq to 9/11.
I also thought about the athletic-dissenters.
I thought about then Toronto Blue Jay Carlos Delgado who refused to come out for the second 7th inning stretch anthem, saying:
I don't (stand) because I don't believe it's right, I don't believe in the war. It's a very terrible thing that happened on September 11. It's (also) a terrible thing that happened in Afghanistan and Iraq. I just feel so sad for the families that lost relatives and loved ones in the war. But I think it's the stupidest war ever.
I thought about then Washington Wizards forward Etan Thomas electrifying a mass anti-war rally in DC in September 2005.
I thought about Steve Nash wearing a t-shirt at the start of the Iraq invasion [that read] "No war. Shoot for peace."
I thought about NASCAR's Dale Earnhardt. Jr. imploring people to see Fahrenheit 9/11.
I thought about the fiercely brave Manhattanville women's basketball captain Toni Smith turning her back on the anthem and igniting a firestorm with her courage.
I thought of Adalius Thomas, Josh Howard, Nick Van Exel, and all athletes who used their platform and spoke out.
But more than anyone, I thought about Pat Tillman. I found myself wondering if the 19 year-olds who were turning Ground Zero and the White House into a frat party last night even knew who Pat Tillman was. And if they did know Pat Tillman, which Tillman did they know?
Did they know the Tillman the NFL wants us to remember – that Tillman was a star safety who turned down a multi-million-dollar contract after 9/11 to join the Army Rangers, only do die in combat 22 months after enlisting?
In the immediate aftermath of his death Tillman became a caricature, used to promote and encourage war.
But the Pat Tillman his family has fought to be known is the actual, thinking, opinionated human being. This Pat Tillman believed that 9/11 had been manipulated to justify an illegal invasion and occupation of Iraq.
As his biographer Jon Krakauer said, "He thought the war was illegal. He thought it was a mistake. He thought it was going to be a disaster. And in the Army, you're not supposed to talk about that. You're not supposed to talk politics. And Pat didn't shut up. He told everyone he encountered, 'This war is illegal as hell'."
He started reading the anti-war theorist Noam Chomsky and sent word that he wanted to meet Chomsky upon returning to the states.
This Pat Tillman died not at the hands of the Taliban but in an incident of "friendly fire", a fact hidden from his own family for weeks after his nationally televised funeral.
Pat's family has spent years fighting to get the true facts of his case known. I thought about Pat's brave mother Mary, and I was just so sad.
We killed bin Laden and all it took was three wars, a million deaths, a trillion dollars, and infinite broken families and broken hearts.
Yes, sports has been co-opted, exploited, scarred, and turned inside out by the aftermath of 9/11 and the hunt for Osama bin Laden.
Some have wondered if now that bin Laden is dead, life will "go back to normal".
But as we saw in Philly last night, this is the new normal and will continue to be so, until every last troop is home.
Maybe then we can enjoy sports as an escape from, rather than a promoter of, this country's culture of war.
