Dwyane Wade's representatives are asking for a two-year, $50 million deal, sources say, leaving the cap-strapped Heat short.
The Mavs, looking to be competitive during veteran Dirk Nowitzki's twilight and beyond, are targeting center Hassan Whiteside and point guard Mike Conley in free agency, sources said.
In addition to keeping free agents Dwyane Wade and Hassan Whiteside, Heat president Pat Riley said his other offseason goal is to see Chris Bosh resume his playing career.
The Heat remained tight-lipped about the health status of Chris Bosh, as well as his future with the team, after the 13-year veteran missed the final 29 games of the season.
Heat center Hassan Whiteside (MCL sprain) says he won't be back for Game 7 of the East semifinals against the Raptors on Sunday.
Miami's Luol Deng is questionable for Game 6 of the Eastern Conference semifinals, while Hassan Whiteside likely will miss a third straight game for the Heat.
