Warriors head coach Steve Kerr was just trying to relax. Lounging on a Hawaii beach on the first day of NBA free agency, his cellphone parked in his hotel room, and engrossed in the nonfiction best-seller "Billion Dollar Whale," the coach probably imagined he was as far away as he could be from the insanity of the news.

That solitude, unfortunately, was short-lived.

These details come from a story written by ESPN's Jackie MacMullan on Thursday, which focuses broadly on NBA coaches' lack of agency in an era when superstars are dictating their futures to a historically unprecedented degree. The story includes reactions from a number of coaches learning the fate of departed superstars, including Steve Kerr's reaction to learning that Kevin Durant was heading to the Brooklyn Nets.
