It takes a lot to admit you're wrong, but that's what Nuggets GM Mark Warkentien did when he wisely shipped career chemistry-killer Allen Iverson to Detroit in exchange for Denver native Chauncey Billups. Iverson, whom Warkentien brought to the team in December 2006, has helped sink the Pistons. Billups — calm, accurate, and willing to play defense and pass — has helped make the Nuggets relevant. That move, and that move alone, makes Warkentien the best of Denver's sports suits.
