Pasta and Elhers current production is irrelevant to Nylander’s contract. What matters is their stats at the time of their signings.
Nylander’s goal scoring is down this season to some horrendous puck luck but he’s also 3rd in terms of total points for the team. Assists matter too.
Goal scorers have a better negotiating position than just points as they're seen as more valuable. Matthews beat Laine for the Calder because Auston scored more goals while Laine had a better PPG rate (but less goals).
Pastrnak put up 34 goals and 74 points in his contract year and got 6.67 mil AAV, while Nylander is on pace for 14 goals and 57 points in his contract year.
Pastrnak is on pace for 44 goals this year ater 1/3rd a season while Nylander will need to have a strong next 2/3rds to hopefully get into the mid 20's.
Presently Lou Lam and Leafs hold the advantage based on Nylander's current stats and projection.
Nylander's agent at present best negotiating position is the possibility of the Cap jumping from $76 mil to $82 mil, so he can get a bigger slice of a bigger pie to divide than when Pastrnak and Ehlers signed their deals despite outplaying Willie as his comparables. That is what his agent will argue anyways.
