GREEN BAY, Wis. -- Jerry Jones has made his share of mistakes, from firing Jimmy Johnson to hiring Greg Hardy to committing countless unforced errors in between. He cannot make another one at Dak Prescott's expense. He cannot do anything during the Dallas Cowboys' upcoming bye week but tell Tony Romothat his time as starting quarterback is done.

At the top, understand that Romo has never been a great quarterback. People throw around that word -- great -- way too easily now. He has been a good-to-very-good quarterback for a long time, this much is true.

But he has never carried his team to a Super Bowl, never mind to a Super Bowl victory, and he has won only two playoff games since taking the job a decade ago. Two. That number is great only in Romo's second-favorite sport, golf, when trying to navigate a perilous par-3.

In other words, Romo hasn't earned untouchable status. He doesn't deserve to be treated as though he'sTom Brady, whose 22 postseason victories and four rings rightfully indemnified him against the possibility that Jimmy Garoppolomight go on the kind of ungodly tear during Brady's suspension that inspired fans and commentators to start asking questions.

But this isn't only about Romo, of course, and a battered 36-year-old body that needs to be handled more delicately these days than a piece of fine china. This is about the 23-year-old rookie, Prescott, who is bigger, stronger, healthier and faster. The fourth-round draft pick just walked into Lambeau Field and played big enough in this 30-16 smackdown of the Packers to make Aaron Rodgers, two-time MVP, look like the incredible shrinking man. Relax? The way Rodgers has performed the past two seasons, I don't think so. In weather conditions the polar opposite of the polar Packers-Cowboys classic known as the Ice Bowl, Prescott threw three touchdown passes to Rodgers' one, ran his winning streak to five, and all but summoned the sights and sounds of Vince Lombardi barking, "What the hell's going on out here?"

When it was over, Cowboys coach Jason Garrett raved about Prescott's composure and poise, and the rookie repeated, on cue, that he still sees himself as a gracious temp. "This is Tony's team," Prescott said, "and I'm just here to help my team win each and every game that I can."

But it really doesn't matter what the coach or quarterback says. The Dallas Cowboys are run by one man, Jones, who is the only owner in major professional sports who holds a news conference after every game. Jones makes the late George Steinbrenner look like a wallflower, and on truth serum, Garrett would likely admit he wishes his boss wouldn't hold these postgame briefings as much as Bill Parcells wished it.
