I know Stern will get little love from many on this site as he made a few decisions that impacted the Celtics in a very negative way, but I will send out my thoughts and deep condolences to Stern's family and friends.
I was a giant Celtic fan in the 70's and there just wasn't a ton of NBA basketball on television. Channel 4 carried games of the Celtics but not every one and the national networks barely cared about the NBA. Heck, I am pretty sure they were showing the NBA Finals on tape delay back and even into the 80's.
But Stern took over and he, with the help of two guys named Bird and Magic, changed the NBA to what we know it today. First Sunday games happened all the time and you got multiple games, much like the NFL. Then the taped delayed stuff ended. Teams started landing lucrative local televising deals. Games started to be broadcast nationally during weekdays. The league became a global phenomenon.
The three point line, the draft lottery, expanded international influence, the Dream Team, lucrative television deals that expanded NBA exposure and the CBA that ensured players got a major piece of the pie all happened because of David Stern.
David Stern made my love of the Celtics and the NBA more accessible and more enjoyable. For that I thank you David Stern and hope you are resting in peace.
