The move is not a surprise since the Redskins have made it public that they were parting ways with veteran QB.
McNabb had a down year in 2010. He completed 58.3 percent of his passes for 3,377 yards, 14 TD's and 15 interceptions. That was good for a 77.1 QB Rating which was near the bottom of the league for starting quarterbacks.
Despite that, the 34-year-old veteran is a significant improvement over the Vikings other QB options. They drafted Florida State quarterback Christian Ponder in the first round this past spring. He is certainly going to be the starter some time down the road. It now appears that it will not have to be this year though. That is big for the Vikes, who have a lot of talent across the board.
They could lose wide receiver Sidney Rice in free agency, but with Adrian Peterson putting the offense on his back, McNabb is still going into a pretty good situation.
Overall they are still probably not as good as the Packers and don't have that good of a chance at winning the NFC North. Despite that, they should now be able to compete with Detroit Lions and Chicago Bears for 2nd and maybe even a Wild Card spot.
Just goes to show you how much a quarterback can impact a team.
