The 36-year-old four-time All-Star, who spent the last five seasons with the Mavericks, would only be able to sign with the Cavaliers for a veteran's minimum contract. Marion had been pursued by the Pacers but his decision to play for the Cavaliers came down to the opportunity to play alongside LeBron James and compete for a championship now.
The Cavs are also widely expected to acquire Timberwolves All-Star Kevin Love this month in a deal that sends No. 1 overall pick Andrew Wiggins and last year's No. 1 overall pick Anthony Bennett to Minnesota. The Wolves would also reportedly acquire the Cavs' 2015 protected first round pick.
The Pacers, on the other hand, lost Lance Stephenson to the Hornets this offseason and Paul George went down this summer with a potential season-ending leg injury while scrimmaging as a member of Team USA.
Last season for Dallas, Marion averaged 10.4 points and 6.5 rebounds in 31 minutes per game, playing in all but six games for the Mavericks. He won a championship with Dallas in 2011.
