It’s universally agreed that Brett Favre will improve the Vikings once he decides to become their starting quarterback. But there seems to be a shortage of hard evidence when attempting to quantify just how much better he will make the team upon his arrival.

Vikings coach Brad Childress said last week that the team wanted to bring in another QB to push Tarvaris Jackson for the starting job. That competition might come from Sage Rosenfels, whom the Vikings are close to acquiring in a trade with the Texans, the Houston Chronicle reported.

Gus Frerotte was successful as the Minnesota Vikings’ starting quarterback last season before a back injury sent him to the sideline. Now, he wants the opportunity to start again.

No new quarterback news Wednesday out of Minnesota, where coach Brad Childress is keeping his decision on who will start between Tarvaris Jackson and Gus Frerotte close to the vest.

Just one of many lingering questions for coach Brad Childress and the Vikings this week is who will start at quarterback.

Brian Westbrook scored on a 30-yard run to put the Eagles ahead of the Giants 10-0. That’s a huge sigh of relief for fantasy leaguers who stuck with the veteran running back. Before that run, Westbrook had 18 yards on 10 carries.

Berrian has really thrived since the Vikings went with Gus Frerotte.

Minnesota quarterback Gus Frerotte injured his hand late in a loss to the Titans when he was hit on a pass.

Last winter, at a time the Vikings were exploring a trade for Texans quarterback Sage Rosenfels, Minnesota head coach Brad Childress kept studying tape of opposing team’s personnel.

In the offseason, Minnesota expressed little interest in trading for Brett Favre. It insisted it had its quarterback of the future in Tarvaris Jackson. But now Vikings coach Brad Childress just announced that Jackson has been benched.
