Are we sure the good run he has had in 11 games this year is the real Blackwood and the inconsistent goalie over the last half decade plus is the mirage? It could be, who knows, but specially with someone like Askarov in the org, I'd rather sell high on him and let someone else make a long term commitment.
One thing about NJD that is super interesting (at least the last few years, haven’t paid as close attention this year) is they limit a lot of shots and keep teams to the outside a lot. Issue is most of their team isn’t strong enough to fully keep them to the outside. So what this results in is 20 shots against per game but most of them are at least chances, there’s not a ton of just throw it on net and see what happens.
Blackwood and Vanecek both seem like what I call volume goalies. I have no idea if this is more of a thing than I realize but basically they do well when they are in rhythm. So while they are facing just as many high quality chances with SJ, they are warmed up and stopping them at a higher rate.
All this to say I think Blackwood and Vanecek are better than they showed in NJ and are getting shit on in SJ because the team is terrible despite they playing actually pretty well.
PS this is supported exclusively by my biased eye test. I have 0 idea how well stats back this up if they do at all.
