Hall of fame basketball coach and longtime television and radio commentator Dr. Jack Ramsay passed away at the age of 89 on Monday.

Ramsay had been battling cancer and stepped away from the broadcast booth because of health issues last season during the NBA Playoffs.  He had been working as a lead analyst for ESPN Radio’s coverage of the association.  Before working for ESPN as a television and radio analyst, Ramsay totaled 864 victories over 2 decades as an NBA coach, including the 1977 championship with the Portland Trail Blazers.

Tributes have been pouring out in social media this morning…

For the generation of fans that knew him mostly as a television personality, Dr. Jack was one of the most identifiable and enjoyable voices covering the NBA.  His knowledge and reliability with viewers were unmatched and he’ll be remembered as one of the best ever on the sidelines and in the broadcast booth.

His son Chris, who works at ESPN.com, wrote a touching tribute which is more than worth your time to read.
