I know he would be behind Nemec and Walsh for PP time and behind Okhotiuk/Bahl, Nemec, Russo and veteran for PK time. Even if he is getting a 1/3 of the 5 on 5, I believe he gets more in the AHL in better situations.
Reading your opinion of how he would be behind so many Comets and therefore not get enough ice time since he would be missing from the key situations of the PP and PK, I admit some confusion. I wonder how you see him passing all of those guys in one svelte swoop onto the NHL roster where better D-men have deprived all those you mention of even making the big club. If Nemec proceeds to be the real deal he is expected to become, he will be on the big club when Mukh returns. Also, one of Ok or Bahl or even both just might be there as well. He will arrive not having had to compete with any of the 3 in Utica or the top 4 in NJ.
If Mukh has the skills and talent I have been led to believe he possesses (though he didn't show them in his very brief stay here during the playoffs last season), wouldn't the coaching staff have the common sense to elevate him to those positions? I'm sure Nemec is going to be afforded those opportunities if he shows he is best suited for the job.
There are no awarded positions by some predetermined pecking order. Players are all in the same pool and where they play and in what situations is first settled upon during camp. Then a kind of show me period takes place and weak play will see another given a shot and so on until the best players for specific situations are identified. He would have just as much chance as the next guy.
Killing penalties often sees all 6 being needed since game situations often require a player not in the top 2 pairs to be called upon: player or players on the shift before the penalty is called have to rest, one of the regulars is in the box, in game injuries shortens the D to 5 guys, etc., That provides a player to show he is very good at the task and he may soon find himself doing a lot of PK duty.
PP situations also see players move around and one player may rise beyond the guy that was originally there. Other times guys screw up enough for a coach to insert a new guy into his 2 PP units. Walsh was not the only PP QB in town last season. That role changed a lot. Russo and Bahl took on the role as well. There were also times when 2 D were employed on the same PP unit.
In short, Mukh is either ready to play over here or he isn't. His ice time will be determined by his play. Another season in the KHL doesn't make him better than any of the guys he is competing against for a job. In fact, if Nemec and one of Bahl/OK excel in their development and Severson is re-signed, Mukh may again be behind the 8-ball. A rebound from the sophomore slump by Smith may jam things up even more. He could come over next season and find himself behind Hamilton/ Severson/Nemec and Siegenthaler/Hughes/ Bahl/OK or even Smith.
When a team is this young and guys are fighting for spots, players can easily see themselves on the outside looking in. It won't be easy for him to just step in and supplant a guy who has established that he belongs.
That can be a negative result of not being on hand to fight for your spot with the others. He will have to be exceptional just show up and push out an established placeholder.
