Joshua Harris can learn a lot from Mark Cuban. Ten years ago - even five years ago - the notion that Cuban could be the model for a prospective NBA owner would have seemed preposterous.
When he bought the Mavericks, Cuban was a brilliant but brash billionaire - a successful businessman who didn't know what he didn't know about basketball. He bristled when challenged and fought (and picked) more fights than was remotely advisable.
Shortly after he took control of the team, I interviewed him for a lengthy profile. I was living in Dallas then and working for the Village Voice Media paper there. We spent a long time talking over several days. Most of the conversations were in his giant, but largely unfurnished, mansion. The story, in the end, was about a bright but eccentric owner, a man who was by turns charming and unnecessarily confrontational.
