At the end of the day for any team, it really comes down to what a 30g/90pt regular season player, total dud playoff player is worth. And he's consistent at both. He also brings baggage with a selfish attitude too, and acts like a baby on the ice as well.
Also remember that his solid regular seasons are propped up by having a team focused on scoring, so he'll rack up assists feeding AM and gang. So in reality, put him on an avg scoring team and he'll drop. Look at Johnny Gaudreau. Guy goes to Columbus with nobody to play with and he's now a 65 pt player now. He only got 60 pts this year.
So you got to be weary about overpaying for players on stacked teams. They likely wont get better going to crappier offence teams. If anything, a higher chance they'll drop.
