“The Birdman” is back in Denver. Chris Andersen, who earned his nickname for his soaring slam dunks, has agreed to sign with the Nuggets, multiple sources confirmed. The 6-foot-10 Andersen, who resides in Denver, played for the Nuggets from 2001-04 and most recently with the Hornets. The reserve will sign a one-year contract for $998,000 and help fill the Nuggets’ void in the low-post.
