Schaap speaks of Muhammad Ali's attempts to try and adjust and change in the world he's plunged into unknowingly, which seemed feeble in the end. Which can be understandable, he was just a normal kid who happened to be a good fighter. It seems you have to grow up in that to really know how to act. It seems Schaap was witnessing something like a lifelong housecoat being forced to live outside, unbeknownst to the dangers and reality of it all.
Although through the course of his life Muhammad's beliefs and ideas changed and blossomed, he still was like a kid. His mannerisms, confidence, arrogance, all parts of him which would never change, and never will. As Schaap put it, he is "so different, but still the same."
