Bill Cowher is not waiting around for a more convenient time to say it.

He's willing to make his declaration right now.

Cowher, "The NFL Today" studio analyst, is not waiting until the Packers win their second consecutive Super Bowl. He's ready to crown their - ah - heads right now, to borrow some of the parlance Denny Green once used.

"Guys, we are watching greatness," Cowher said on Sunday. "In my opinion, no team has been greater. You know what? You can pick and say well, the defense (is not great). They have never trailed in the fourth quarter in these 18 games. You are going to give up some yards. They take the ball away. You are watching the greatest team in football history unfold before our eyes. Let's enjoy it. Let's embrace it."

Cowher's colleague, Boomer Esiason, questioned Cowher's judgment.

"Did you just say the greatest ever?" Esiason said. "I don't agree with you because I don't think their defense is the greatest ever. Their offense is one of the most dynamic we have ever seen. But I will say this. They have playmakers all over the roster. . . . But the greatest ever? I can't go there yet. When they get to back-to-back Super Bowls, then maybe we can talk about it."

Host James Brown said Cowher is not one given to hyperbole.

"I am just telling you right now, I'm watching a team that has the swagger, they have the look, they have the belief and they have the edge," Cowher said. "Yes, I am saying it now. You can say it afterwards, but I'm saying it right now."

Shannon Sharpe said the 2007 Patriots were perfect, until that time when the Giants beat them in the Super Bowl.

Cowher said the only team that can stop the Packers is the Packers.

"We saw New England (in 2007) trending down downward," Cowher said. "You remember at the end of that season and during the playoffs, they were trending downward? I see no trending (downward) for (Green Bay). I see the best quarterback anyone has ever had in a season."
