Avery Bradley has changed agents from Mitchell Butler of the Rival Sports Group to Rob Pelinka, who also represents Kobe Bryant. Butler was able to procure the oft-injured Bradley a four-year, $32 million contract extension last summer, considered an above-market deal. Now Bradley is apparently unhappy with his contract, especially after seeing players such as Milwaukee’s Khris Middleton (five years, $70 million), Utah’s Gordon Hayward (four years, $61 million), and Cleveland’s Tristan Thompson (five years, $82 million) cash in with lucrative extensions, making Bradley’s deal appear to be a bargain with the new television money increasing the salary cap this summer.
