16. Dikembe Mutombo to the Sixers
Trade: Atlanta Hawks get Toni Kukoc, Nazr Mohammed, Theo Ratliff, and Pepe Sanchez; Philadelphia 76ers get Dikembe Mutombo and Roshown McLeod.
When the 76ers acquired All-Star center Dikembe Mutombo, you would've thought they had to give up a lot to acquire the veteran. But they gave up perennially injured Theo Ratliff, the past-his-prime Kukoc, and a young Nazr Mohammed. With the acquisition of Mutombo the Sixers found themselves with the best record in the Eastern Conference and in the 2001 NBA Finals, while Atlanta didn't make the playoffs again until 2008.
