Parayko is not nearly having as good a season as he did last year, but with a more offensive minded team could get more + and points while still playing his defensive style of hockey. also parayko is fairly young with a good contract and could really make a difference for the leafs come playoff time

Nylander might be having a career year because of the players he is on a line with, which could be a big risk factor. on the other hand he could also get better with development on the blues, as he is still a young player with a lot of talent. it also allows the blues to add more offence and youth to they're team.
