NBA Free Agency begins today at 5 pm CT. Kevin Durant has just requested a trade from the Brooklyn Nets; very few players of this caliber with four years left on their contract have ever been available for trade. Kyrie Irving is expected to be traded as well. In other news, Jalen Brunson is expected to receive a massive offer (100 million-plus) from the New York Knicks, but the Dallas Mavericks may lay a 5-year deal on the table for their coveted point guard. The Philadelphia Sixers will pursue Maimi Heat's forward, P.J. Tucker. Meanwhile, the Chicago Bulls want to add a defensive center, such as Mitchell Robinson.
