The ESPN announcement seems to have come early, to be honest. The last time there was a switch in carrier, NBC made the announcement in May 2004, in the middle of the playoffs, and right before The Lockout.
All attention is going to be on the trade deadline right now, plus the mess in Vancouver. My uneducated opinion thinks nothing gets announced until those situations get settled.
As for any news, the quieter, the better. That usually means negotiations are in progress. I still think we’re looking at a 51/49 chance of NBC or Fox for the B Package.
