The Sports Business Journal has some interesting details on Fox's plans to potentially turn its Speed network into an all-sports channel as early as 2014. It would be a single national sports network like ESPN rather than be like its current regional Fox Sports Net channels. Speed is already in over 80 million homes, which gives it wider carriage than CBS Sports Network and NBC Sports Network (formerly Versus). I would love to see someone give ESPN some really good competition, but based on what I've seen so far from Fox, I doubt this potential network is going to be it.
