A good way to sell a book is to write interesting details about someone famous. And when you’re actually related to that famous person, you probably have some decent stuff to share. Stephon Marbury for a long time has been known as a “me-first” kind of guy, and that’s probably sometimes been unfair. But his own cousin has joined in and shared stuff that helps solidify that reputation. Here’s the New York Daily News (Mark Lelinwalla):

Stephon Marbury has carried the stigma of being a selfish player for the majority of his 12-year NBA career. Now, his older cousin is saying Marbury is even more self-centered off the court and is dishing details on the Knicks point guard in his autobiography, “The Beautiful Struggle,” the Daily News has learned. The book, due out in late September from Xlibris Publishing, has former NBA pro and current overseas player Jamel Thomas alleging that Marbury ruined a potential deal for him with the Minnesota Timberwolves. In it, Thomas includes a conversation that he allegedly had with Kevin Garnett, in which Garnett tells him how Marbury’s presence on the team spoiled his cousin’s chances of signing with Minnesota.

For all you fans who watch every basketball movie that comes out, you’ve seen a little of Jamel Thomas already in the Sebastian Telfair documentary “Through the Fire,” which I really liked. Anyway, as someone who covers the NBA for a living who is also a New Yorker, I’ll definitely be checking the book out and will let you know how must-read it is.
