Tony Romo's Updated 2013 Fantasy Outlook and Trade Value After Week 4

Who is this, and what has he done with Tony Romo?

Although the Dallas Cowboys ultimately lost against the San Diego Chargers, Romo had his third straight game without an interception. He had a similar stretch last season, but it was bookended with four-INT and two-INT performances.

The 33-year-old finished the game 27-of-37 for 244 yards and two touchdowns. It was the kind of steady Romo we have seen all season.

His completion percentage of 72.2 is 7.2 percentage points above his career average. The highest of his career is 69.5 percent in 2010, and that's when he only played six games. The fact is that—all of a sudden—Romo has become a reliable quarterback.

What's really working for Romo this year is Dez Bryant. He's never had a weapon like this in the passing game. Jason Witten and Miles Austin are steady receivers, but they don't offer the big-play ability Bryant does.

He and Romo have formed a great combination close to the end zone, via ESPN Stats & Info.

Selling high is certainly something that comes to mind from a fantasy perspective. This is a guy who's thrown fewer than 10 interceptions in only two seasons as a starter, and one of them was in 2010. Romo isn't going to become a vastly different quarterback now.

Expect some regression to the mean in the coming weeks.

If you've got the Cowboys QB on your team, you might want to see what's out there on the trade market. Don't just settle for a less-than-fair deal, but you should definitely pull the trigger if another owner is willing to offer a ridiculously good deal.
