I ss them in Charleston WV in the 1960's, then read a book about them featuring their owner, Abe Saperstein, who led them in their barnstorming tours around the country.
The weaves and stall tactics evolved because in the early years the basketball courts in some small towns was actually the local swimming pool that was drained then with baskets placed on the ends. During halves where they end of the court was going up hill they would stall. On the halves where the Globetrotters had the down hill slope that would heavily fast break. I am not making this stuff up....
