I have no idea what is being negotiated, or why its taking time however i could only assume that Fox, with a 5 year deal in place would be continuing with similar coverage. There has been nothing to suggest they will scale back coverage, after the league has just come off one of its best seasons on and off the court.
The FTA component has traditionally always taken up the entire off season to finalise. Didnt the channel 9 deal come right at the last week of the offseason?
The SBS deal looked like it was slapped together at the last minute too.
Honestly, I would be stunned if there was no FTA offering this season. Id say the league are working on getting something a little better than SBSs coverage, with Fox to stay the same.
