That is a ton of points for a guy that wouldn't be on any good team's #1 PP unit. Granlund going from #1 PP on San Jose to #2 PP on most contending teams alone is going to cost him about 15-20 points a season alone. Look what he was producing for Nashville when he was on their 2nd PP unit, he had 6 PP points in 2019-2020 and 7 PP points in 2020-2021. If he's not putting up 25 PP points a season, he's topping out at about 45 points while still getting 1st line minutes at ES. Which is what he has shown with literally every team he has been with in his career.
And the idea that he'd be the "best 3C in the league on a stacked team" has been proven factually untrue when he was brought to the Penguins to be a 3C behind Crosby and Malkin was was horrendous in the role.
Last year with San Jose, Granlund was 29 of 308 in the NHL in 5v5 ice time per game (among forwards with more than 700 minutes TOI) but was 151 of 308 in 5v5 points/60 (among forwards with more than 700 minutes TOI). And that was his best 5v5 performance in years, it was a middle of the pack production rate that just had him producing points with a ton of ice time. In 2022-2023, he was 259 of 301 in 5v5 points/60.
