I believe the Titans are the only NFL team not included on the NFL's deal with Sirius. You can hear Titans games, but it'll always be the opposing team's broadcast (or national broadcast, like Westwood One). Why the Titans aren't invovled with the deal, I have no idea.
I believe the issue is with the Titan's host broadcaster. They appearantly take the anti-satrad doctrine of the NAB very seriously.
Yeah but why Sirius' deal with the NFL doesn't over ride that is the question here. Other stations feel the same way but they still get forced to give their feeds up.
