I think PK would be energized to come back to Montreal. He loved it there and i think you could see an uptick in his play if he returns.
He is a right shot defenceman, which is in demand in Montreal.
At this stage in his career he would not be expected to be "the guy", he would just be a quality addition to the defence as a 2nd or 3rd pairing player.
If you pro rate his stats from last year he was on pace for about 35 points. Not bad for a D. I acknowledge that the points likely came as a result of being given top pairing minutes in NJ, though. Nevertheless, i think Subban on the 2nd or 3rd pair will still get more points than Kulak will likely ever get. Kulak may bestronger defensively, but not substantially.
With respect to draft picks some people tend to overvalue picks after the first round. If you do some Google searching about the likelihood of a draft pick playing more than 200 games in the NHL you will see that picks in the 3rd round and later have a low rate of success. Of course there are always exceptions to this and some real stars are found in the later rounds, but the math is what it is.
In this scenario I even left Drouin on the team, which I almost never do in any of my other posts. I am still very skeptical about him though.
Reasonable approach for Montreal (and NJ) or no?
Does Montreal need to add or subtract to make it happen?
