No, maybe for PR reasons they probably shouldn't, however, we don't necessarily know the whole story either.
While I agree that loyalty and respect are important, it should also go both ways.
With the information we currently have (which may not be the whole story), it's not apparent that Troy kept the team abreast of his situation and let them know whether he was going to show up for the game or not. I get that from some comments made by Childress late last week, when he said he didn't know the current situation with Troy and didn't know if he would be there on Sunday.
I understand Troy's situation and can sympathize with his feelings. However, I also understand the Vikings' side of the situation, and can take that into account as well. Unfortunately, it was leaked to the local media, and if you know anything about the Twin Cities media, they jump on little negative items in stories like Drudge does on about Hillary not tipping an Iowa waitress. They don't get the whole story. That's partially why Denny Green refused to talk to the local media for the last 7 years that he was the Vikings coach.
