I don't disagree with that, but you're ignoring recent history, and the focus is on the Lakers right now, the heat is off the Kings, they have more recent championships and an excuse for current suckage.
Agree that they'll start making a splash again next offseason, and that'll be more in line with what you saw from the Rangers, who attacked from all angles (Trouba, Fox, Kakko, Panarin all very different types of acquisitions).
But hockey has traditionally been the exception in LA, it's not like the other sports where you can go out and get a Beckham or a Lebron and a big name makes you money by default. Hell even baseball has morphed a little bit, I know more people that would have been upset with Bryce Harper (contract, at least) than happy.
