Say it ain't so, Jerry — say it ain't so …

In 2006, when Jerry Jones brought wide receiver Terrell Owens to Dallas, no one was happier than me.

I once again had reason to root against the Cowboys, an often entertaining pastime. And T.O., with his narcissistic whining, made rooting against “America’s Team” ever so worthwhile. Last year’s signing of the thuggish Pacman Jones was like adding whipped cream and cherries to an already mouthwatering sundae.

Last season’s implosion — with Pacman’s suspension and Owens’ verbal undermining of certain Cowboys teammates — was especially delicious.

But early in this off-season, Jerry Jones cut Pacman. And now he’s released Owens.

I feel bereft. Who am I to root against now? Tony Romo — who stops and changes tires for strangers? I think not. And if the Cowboys owner is wising up about the importance of character and chemistry and essentially admitting his mistakes, what joy can I even get rooting against him?

Life is so unfair.
