Exactly, he didn't want to be in the spotlight. In fact, he hated being in the spotlight. I remember somebody saying that Marvin is so afraid of public speaking that he said the only good thing of possibly not being inducted into the HOF would be that he wouldn't have to make a speech in front of people.
I think he is humble. He seems like an old fashioned type of business man that values respect over all else. Perhaps a more fitting word be noble.
You are a petty wannabe gangster. Marvin Harrison is a fucking don. He is running shit without ever being seen. You are running around pistol whipping nobodies and doing time for it. You are a small time petty thief, and a shitty one at that.
