The Action Network's Darren Rovell joins Jimmy Traina on the SI Media Podcast to discuss the explosion in the trading card business. Rovell goes in-depth on explaining the many aspects of the trading card craze, including why the boom happened, whether it will last, and the process of getting cards graded and sold for profit. And it's not just cards that are in high demand, as Rovell explains that people are also buying and selling game tickets, VCR tapes and checks. In addition to discussing the trading card world, Rovell and Traina also talk about the Super Bowl streaker who claims he won $375,000 on a $50,000 bet, and the possibility of Twitter adding a pay service.
