Carter, 37, will be an unrestricted free agent this offseason. He spent the first seven seasons of his NBA career with the Raptors, leading them to the playoffs three times.
For the past three seasons, he has been with the Dallas Mavericks, where he signed a three-year, $9 million deal in 2011.
Carter averaged 11.9 points, 3.5 rebounds and 2.6 assists for the Mavericks in 2013-14.

Be advised that Carter has been very happy in Dallas these past three seasons. Very happy. He's emerged as the emotional leader of Dirk Nowitzki's team at this late stage of his career and, by all accounts, wants to re-sign with Dallas.
