Another hoops record that will not be broken any time soon. The Celtics’ dominant run spanned 1959-’66. It’s also the longest championship-winning streak in United States’ professional sports history. While those Chicago Bulls teams of the 1990s were quite impressive with six titles over an eight-season stretch, it still does not compare to what Boston was able to pull off.
