I'm sorry you find it to be circular talk, but it is what it is.
Good teams do find ways to keep their good players, but caps are in place and at some point you're not going to keep all of your good players. At some point you end up having to find other good players, who can fit within the cap structure. And those changes aren't always of the 1 for 1 variety. Sometimes it's having a $4 million LD and a $3 million RW instead of the $7 million LW. Sometimes it's dictated by the $11.5 million LW you signed 9 months prior, or the $3 million raise you have to give to someone in a few months.
I don't think the more immediate focus is on replacing Kreider, it's trying to figure out how to get as many puzzle pieces into the right place, at the right time, while utilizing a finite pile of resources.
