The problem I have is, and I hope someone made this clear to him early on, is that the Rangers are not going to change their position. Assuming the best case scenario that he goes back to the KHL and dominates the Rangers are never going to say to him - "Hey, Vitaliy, remember that Hartford place you really don't want to play for? Well come back now and we promise you'll never go back there again." He's never going to get that guarantee.
It's not like the Rangers tried to reinvent the wheel with him. He obviously isn't NHL ready, especially not for a top 9 role. So what were they supposed to do? All he has to do is look around at other players in the organization to understand what's happening. He's playing with another highly touted European prospect and first round draft pick in Filip Chytil who is going through the same exact process and doing it successfully. Is it possible nobody said to Kravtsov - "Hey, you see Chytil? He's going to be in the Show soon - do what he's doing and this will work out." He's playing with another highly touted countryman in Shesterkin who, despite possibly being the best goalie outside the NHL, has absolutely nothing guaranteed to him with Lundqvist and Georgiev ahead of him on the depth chart.
I just don't see what is going to change to alter the status quo. Is Kravtsov going to become amenable to possibly playing in the Always Hungry League after a year or two in the KHL? Anything can happen I guess and I hate to be all doom and gloom but I wouldn't be in the least bit surprised if he stays over there, has a great KHL career and a great life surrounded by family and friends.
