Former NFL All-Pro suggests a trade for Tony Romo that would make the Cowboys next year’s Super Bowl favorite

This could be the biggest player-for-player trade ever in the NFL, if it came about

You don't see many player-for-player blockbuster trades in the NFL —- it's hard to get equal value for truly great players —- but Chris Carter has proposed a dozy.

He thinks the Houston Texas should go after Dallas quarterback Tony Romo, and offer J.J. Watt as bait.

"Where Dallas is, they have a lot of good, young players," Carter, the Hall of Fame receiver turned broadcaster said on the Skip and Shannon Show. "So I like an established player. And if you trade (Romo) to Houston, I would try to get one of their defensive players. I'd try to pull off a deal for  J.J. Watt."

Wouldn't that be something? That could go down as the biggest player-for-player trade in NFL history. The biggest trades in NFL history —- Herschel Walker to Dallas in 1989, John Elway to Denver in 1983, Steve Young the the San Francisco 49ers in 1987 —- were primarily player for picks.

True, Watt had back and groin issues that limited him to three games last season, and the oft-injured Romo is soon-to-be 37 and the back nine of his career.

But, if those players can stay healthy for their teams for one year, the Texans get a quarterback who could help them challenge the New England Patriots dominance in the AFC; and Watt, a three-time Defensive Player of the Year, would bolster a defense that already ranked first against the run —- and could make the Cowboys the Super Bowl favorite.
