It's pretty easy. We have some good players and many horrible players. Sam reinhart is the former.
When 2 guys have similar stats and one plays on a very low scoring team and one plays on a very high scoring team, it stands to reason the guy with similar stats on a low scoring team would see an uptick if he switched places with the other guy
except that it's a thing with literally every leaf trade vs a bad team player "well, mitch marner isnt worth that much because he plays with matthews!" every time. And then "well, eichel is worth more because he plays with whoever".
Just once id like to see the Leafs players get some credit for making the team better or something instead of "but tavares is on that team!" or "oh, Kerfoot is worth a 3rd rounder because of the leafs depth, but sam bennett is worth a 2nd!" or some crap. it's a bad excuse and poor context most of the time.
As far as Nylander VS Rienhart, the last 3 seasons is an interesting cut off considering it hacks off one of Nylander's best seasons, includes his worst while Rienhart gets all three of his best seasons. then we also get to the part where Nylander is better defensivly and a much better goal scorer and does it with 2-5 mins less of ice time per game.
but back to the point. The Leafs dont trade that for Sam Reinhart even if it is a 'fair' deal because they dont need Sam Reinhart.
