Free-agency update: Denver staying busy

Posted by ESPN.com's Bill Williamson

The first hours of free agency are cranking hot and heavy. But the AFC West has been fairly quiet.

Most of the news is coming out of Denver where the Broncos are looking to add new pieces to the puzzle -- not major pieces here, more like complementary pieces.

Receiver Jabar Gaffney is visiting Denver. He played for new Broncos coach Josh McDaniels in New England. He would be a fourth receiver behind Brandon Marshall, Eddie Royal and Brandon Stokley.

The team is also hosting running backs Correll Buckhalter and J.J. Arrington, who would both will be role players. Miami safety Renaldo Hill is also visiting. All of these players could sign with Denver soon. Denver needs safety help and the steady Hill would be a good start.

Meanwhile, in San Diego, there are rumblings the Chargers may bring back Drayton Florence. He went to Jacksonville as a free agent last season but he was recently cut. Florence has already visited Buffalo. He'd be a role player in San Diego.

There was some talk that Kansas City could get involved with linebacker Bart Scott but he has already agreed to terms with the Jets. The Chiefs, as they have been in every aspect of their operations this offseason, have been quiet in the early hours of free agency despite having more than $50 million in salary-cap room.

Here's a name to keep an eye on in Denver: Marques Douglas. The defensive end was just cut by Baltimore. He played for new Denver defensive coordinator Mike Nolan in both Baltimore and San Francisco. The Broncos have a need for a player such as Douglas. This could be a perfect fit. Nolan is also trying to get defensive tackle Ronnie Fields, who played for him in San Francisco.

Signing players who are familiar with Nolan's system will be important as Denver transitions to becoming a 3-4 defense.
