I'd come into negotiations and just lay it down like- I think we can both agree McDavid is the best player in the world he's going to be the highest paid player on the team and Draisaitl isn't too far behind him he's going to be the 2nd highest paid player on the team, Nurse you're going to be the 3rd highest paid player on the team. Then you negotiate from there setting the bounds between I guess what will be Hyman's deal and Draisaitl's deal, with Nurse ultimately being much closer to the Drai end of the scale.
Given that McDavid, Drai, and Nurse are all close and the other 2 have clearly been our better players for a prolonged period of time I don't think Nurse can really argue that he deserves more than Drai. As long as his camp can agree to that basic premise I think negotiations should go relatively smoothly.
