The thing about blowing up the Grizz is that this is something that has been assumed would happen since they signed their 3 stars. It was assumed that their market couldn't handle the three max or close to max contracts for an extended period, and most of the analysts assumed that they just signed them all to maintain their value, but then eventually trade one or two of them.
So, I am not sure this is really a change in philosophy, I just think the pressure is on now that the new luxury tax is kicking in, and they need to finally pull the trigger.
