DIKEMBE MUTOMBO. This man has donated a substantial portion of his time and income to building hospitals and other projects in Africa and here in the U.S. He was known for his shot blocking ability. He's about 7 feet 2 inches tall. So, that was his specialty. Defense. My buddies didn't like him because he would stop the more flamboyant, exciting players, like Jordan, from scoring. I liked him when I was a child and still do.
