So is it a coincidence that on the same day that a veteran receiver with extensive experience in the West Coast offense hits the market a free-agent receiver who played for one of the teams using that offense in 2007 suddenly re-signed?

We think not.

The Vikings have inked Robert Ferguson to a one-year deal 15 days into free agency, after Ferguson drew some interest from Chicago and Pittsburgh but visited neither city.

The move came in the wake of the release of receiver Darrell Jackson by the 49ers.  Before one year in San Fran, Jackson spent his entire career in Seattle.

Ferguson’s deal is for one year and $1 million, with the ability to make up to $600,000 in incentives.

But Ferguson isn’t out of the woods just yet.  The Vikes could still bring in Jackson, and decide between Jackson and Ferguson during training camp, or after the preseason.

Ferguson joined the Vikings in 2007 after spending six seasons with the Packers.  He was a second-round draft pick in 2001.

Minnesota now has Bernard Berrian, Bobby Wade, Sidney Rice, Aundrae Allison, and Ferguson at receiver.  Ferguson also is the first of the Vikings’ own 2008 free agents to return.  Five have left, and three are still unsigned.
