One of the great forgotten NBA players is Tommy Heinsohn. He came to the Celtics in the same draft as Bill Russell.
He was a brilliant offensive performer and was well known for a low jumper and a hook shot. Heinsohn learned how to play in a gym with a low roof and his shots never had much arc.
Still went in a lot.
We know him mostly as an announcer and before that he was one of the best coaches the Celtics have ever had.
Check out this video look back at his career.
