Meanwhile, according to a source, Arturas Karnisovas, the Bulls’ new head of basketball operations, and new general manager Marc Eversley have already had detailed discussions with players and retained front-office personnel — and are getting enough mixed feedback about the last year that they’re said to be leaning toward starting fresh with a new coach once the NBA decides how to resolve this season. Barely a month on the job, Karnisovas walks a fine line between pleasing the Reinsdorfs and reminding them that this new front office was hired with the promise of full autonomy and trust on basketball-related decisions.
