From what we can tell, this photo only started making the rounds yesterday, even though the Spurs night out on Halloween had been well-documented otherwise. These are the same costumes Tim Duncan and Tony Parker wore then—Duncan as the Punisher, because of course he'd pick a relatively obscure comic book antihero as his Halloween costume. Both Parker and Duncan used guns as props for their costumes, though the noose doesn't seem to have factored in elsewhere. At least one message board poster has suggested that the picture was digitally altered (though his signature reads, "San Antonio Spurs 2013 Champion Crew"). No word on who the faux-Crawford might be, but he pretty much nailed the role.
If you're in the dark as to why it might be fun for the Spurs to exact a little pretend revenge on Joey Crawford, recall this, from April of 2007:
Crawford ejected Duncan from San Antonio's loss to Dallas on Sunday after calling a second technical foul on the Spurs star while he was laughing on the bench.
"He looked at me and said, 'Do you want to fight? Do you want to fight?"' Duncan said after the incident. "If he wants to fight, we can fight. I don't have any problem with him, but we can do it if he wants to. I have no reason why in the middle of a game he would yell at me, 'Do you want to fight?"'
Video of the incident here—it and other conflagrations have led some to argue that Crawford shouldn't be assigned to Spurs games.
The league just finished grappling with a Spurs infraction of a different stripe, levying a $250,000 fine against the team for resting its stars—Duncan and Parker included—in a nationally televised game against the Heat on Thursday.
