According to a report from The Athletic's Shams Charania, tensions were running high between James Harden and Chris Paul during their season-ending Game 6 loss to the Warriors. Things boiled over behind the scenes as the two star players had a "verbal exchange" outside of the public eye as they made their way to the locker room.  

The exchange reportedly ended with the two athletes storming off after being separated. Charania's report shed light on the tension brewing between Harden and Paul, revealing that Paul has been pushing for ball movement in the Rockets' offense. Harden often isolates and goes 1-on-1, which goes against what Paul would like to see.
