Per Yhaoo’s Adrian Wojnarowski, The Miami Heat are in serious discussions with former Golden State Warriors and Sacramento Kings Head Coach Keith Smart on joining the Miami Heat coaching staff as an assistant coach. Last week Miami shook things up with the coaching staff by reassigning assistants Bob McAdoo and Ron Rothstein, while elevating player development personnel Juwan Howard to assistant coach. Smart has been out of coaching since his last stint with the Sacramento Kings in the 2012-2013 NBA season.
