Verizon Wireless (VZ, VOD) is apparently doubling down on its pro football bet. The WSJ reports Big Red and the NFL have reached a 4-year, $1B extension to their current deal that will result in every NFL game being available on Verizon smartphones via the carrier's NFL Mobile service, including home market and playoff games. The current 4-year, $720M deal only provides access to a subset of games. No details on tablet support - for now, NFL Mobile only provides tablet live video access to Verizon FiOS and Cablevision subs. For non-Verizon subs, there's always the Slingbox.
