Quoting: Daryl
Spurgeon eats up 24 minutes a night, and has a positive CF% rel unlike both of Zaitsev and Brown. Spurgeon isn't a franchise D but he's a quality puck mover which is an asset the Leafs would very well use.
You're getting hung up on individual players here. I'm not arguing that Spurgeon isn't good. He's fine, and I'd be happy to see him on the Leafs. However, my point is the trade you proposed weakens the Leafs. Its not a net positive move. It improves 1 pairing of the defence, weakens another, weakens the forwards and weakens future depth by trading an asset.
On top of all that, TO is in a massive cap crunch next season (Only next season however) so the Leafs need to be really smart with their assets. This trade does more harm than good, which is why I am saying what I am saying.
Think big picture always, individuals are part of that picture but if you can't look past the individuals you end up with a shitty team. Just look at Edmonton, they made trades based on individual issues and then traded Hall for Larson. That's what happens when you think about specific players in a trade instead of the overall state of the team after a trade.
So in conclusion, if you really want Spurgeon, make a trade is fair but also doesn't harm the team.
