They can still flourish on the Rangers. It's wild that any NYR fan would want them to do well somewhere else just to say "Look I was right, this organization is the worst and a complete failure. I can't wait to keep watching the rest of the season and beyond to see how badly they do."
Both Kakko and Laf are still young, they're still learning to play in the NHL believe it or not. Neither were completely developed players or humans when they were drafted and they still aren't. Would everyone have liked both of them to be 60+ point guys out the gate? Of course. Does it feel disappointing given draft positions? I guess. According to some of the posters in the know around here, there isn't much imminent concern in hockey circles about how Kakko/Laf are progressing so I'm more inclined to exercise patience with their development. There are flashes and Laf has had some pretty big moments. I have faith that eventually both of them will turn that into consistent play, but it will take time and patience to handle the growing pains that will happen.
