MIAMI — So who is Bernie Lee, the agent for Miami Heat forward Jimmy Butler, the representative who has put himself at the forefront of recent trade speculation fostered by ESPN regarding his client’s future? More than anything, he’s a passionate (sometimes overly passionate) defender of his clients and a presence with a high visibility around the franchise for decades, dating to the his representation of guard Mike James, who emerged from an undrafted walk-on with the Heat in 2001 and went on to an NBA career that lasted more than a decade. Amid conjecture about Butler’s future, conjecture that largely had been dormant until a report earlier this week by ESPN’s Shams Charania, Lee took to social media this week to debunk reporting of actively seeking potential landing spots for his client, who has the right to opt out of the final year of his Heat contract this offseason. In the wake of that back and forth on social media, an amused Butler interjected his thoughts following Thursday night’s 114-104 victory over the Toronto Raptors. “I love it,” Butler said when asked about Lee’s pointed rebuttals, where the agent disliked his name popping up in the conjecture about Butler’s future.
