Any personal attacks are inappropriate, and really have nothing to do with the current situation.
That being said, I think it's reasonable to question his relative value to the team because we have the offensive depth to compensate for his absence, and there is a glaring need to upgrade the blueline. It's no slag on him as a player. He would be a top 6 forward on any team in the league.
The most fair way I can describe Nylander's situation is his importance to the rebuild has been in decline since the playoffs last year when he played a soft game head to head against a comparable talent, contract and young sniper in David Pastrnak who thrived head to head.
I'd acknowledge that plans are always changing, and the dream of the Big Three suddenly looks like Matthews, Marner, Tavares. Nylander is sort of surplus and a bit of a luxury. I'd also acknowledge that trading him for an appropriate return would alleviate our depth chart issues, redistribute our cap to other positions and wouldn't take away from the ridiculous strength we currently possess.
That said, I still am a huge fan and would like to see Nylander sign a "dynasty friendly" contract under his asking price, because the long term health of the Leafs and the "band" is more important than just having Nylander here. I just don't see any villains in the whole process. If there isn't a magic number that makes both sides happy, the Leafs will have to move on.
