LS is correct. The Sharks have tried to get out of it, but no dice.
While the contract SUCKS, I think it's nice that the Sharks get to sit back and see how these teams far with non-RSN options like teams with all games on OTA, all on streaming (like the Stars with free streaming), or hybrid, before the Sharks dive into something like that. There's going to be lots of kinks to work out, especially for something like what the Stars are doing.
I would bet the Sharks would be closely monitoring how the Stars set up goes, because I suspect that's what they might be thinking (free, but only streaming with no OTA games).
