Tristan Thompson and the Cleveland Cavaliers have stalled in their extension talks ahead of Friday's deadline.

Thompson is represented by Klutch Sports and LeBron James' agent and business partner Rich Paul.

James holds extreme power within the Cavs organization, and he played a key role in advising on the trade that brought Kevin Love to the team for a package that included No. 1 overall pick Andrew Wiggins over the summer.

Recently, James inserted himself into the talks with Paul client Eric Bledsoe when he encouraged the Phoenix Suns to increase their contract offer via social media.

Both league executives and agents are closely watching how the Thompson talks play out as a gauge for how involved James is making himself in the team's front-office moves.

Thompson also has a positive relationship with Dan Gilbert, who advocated for selecting him over Jonas Valanciunas.

The sides both remain hopeful they will get a long-term deal with Thompson worked out this week, sources said.
