As if Stephon Marbury weren't having enough trouble — and hey, who's having more trouble than a guy making $20 million while "rehabbing" an "injury?" — he's now being called out by old Coney Island pal Jamel Thomas.

Thomas, whose NBA career could charitably be called "brief," is supposedly writing an autobiography, the outline of which he details in this YouTube clip. He has some harsh words for his "cousin," words that will surely be transferred into a bestseller. Prepare for the bidding war.
