Mike Piazza's $13 million a year salary, currently the tops in baseball, isn't likely to stay No. 1 for very long. The current crop of free agents, who could begin negotiating with current and new teams last week, is considered the best in years and observers -- and agents -- are saying the top salary for a Randy Johnson, Kevin Brown or Albert Belle could reach $15-$16 million. Note: the entire salary of the major league rosters of the Marlins and Expos last year was BELOW $16 million.
