I know I'm in the minority but If our top 6 does what they are capable (even our top 9) I would be more than ok keeping him in the KHL next year as well. I just don't want him coming over here later this year and playing on the 4th line or being scratched.
He's still only 20.
Personally I think it would be good if Kravtsov came over after his KHL season is over (including playoffs). The benefit would be
1. Continuing to learn from participating in practices and getting advice from the coaching stuff and players
2. There's nothing wrong with getting limited 4th line minutes - easier competition against and keeping attention on the defensive side. A lot of players (eg. Buch) spent time on the 4th line until he was moved up on merit. This could also push those ahead of him to play better. Competition is good
3. Being insurance policy in case of injury to those in top-9 spots
