To be fair, WOWY stats are designed to mitigate these effects. Those numbers track the difference in corsi when on the ice with specific players. When you look at each player's WOWY stats, you can get a general idea of who is carrying their weight.
That being said, at 5v5, MacDonald plays the bulk of his minutes with Simmonds, Schenn, and Lecavalier amidst one of their weakest 5v5 stretches of the year.
On top of that, I still hate using corsi for players like LSchenn and MacDonald. These are players who defend by blocking shots, and corsi classifies blocking shots negatively. I'd be more interested in their fenwick stats, but I'm too lazy to look it up.
Advanced stats are useful, but they are not gospel. There is a lot they don't account for. Sure, he may be a negative corsi player, but that doesn't account for the weight of his good and bad plays. A lot of what MacDonald does well, he does better than anyone else on the roster. For example, his ability to retrieve the puck in the D zone and navigate out of trouble is excellent. That's been a phenomenal improvement on our D core, and advanced stats don't shed light on it. Though their proponents will tell you that all these skills are inherently included in their stats. I'm not convinced. Especially when you're playing with weak 5v5 forwards.
EDIT: I do agree with one thing in that article if nothing else, Gustafsson deserves to be in the lineup.
Just checked extraskater.com, his Fenwick For/60 at 5 on 5 is at 3.8 for the year. The top pairing, Norris caliber guys seem to be hanging around 8 or so. Matt Carle, who I feel like MacDonald is sort of a replacement for is at 5.5. Unfortunately, extra skater only shows his season with the Islanders and Flyers combined. I can't find numbers for his time spent in Philly, alone.
Grossmann's FF on the year is 5.4... A career high.
I'm interested in advanced statistics, and I read about them a bit. I think they're getting more useful as time goes on, but in this case, I think it shows that there's still a lot of room to grow. MacDonald's puck retrieval skills, and his first pass, might be the best on our team right now. He's not an all star, but to say he's detrimental to the team is absurd. There's a reason that players like MacDonald are getting overpaid as soon as they hit the open market.
As far as the "highlight" video goes, you can do that to every player in the league. Hockey is a game of mistakes, and every player commits them. Every single goal that's scored in the league, is a result of a mistake, somewhere by somebody. It's not a travesty that a 2nd pairing defensemen could get turned inside out by Patrick Kane or JVR - those guys are big time scorers for a reason - and it shouldn't be MacDonald's job to shut them down. Let him do what he does well, and it should pay dividends.
Edit: Just saw this comment on BSH...
Grrrreaaaat article. AMac is exactly who he was projected to be. He’s just plain bad. We had a chance to go after someone that would have been an improvement over Gus, and we got AMac instead. For every good move Homer and his staff make, there are deals like this one where you want to put a fork in your eye.
Anyone who can’t see that from his play thus far is just trying to blow sunshine, and I understand the desire to look at the bright side and not be a Negadelphian, but the scary part of this, is that Berube is so smart, he’s sheltering AMac effectively to the point that he actually looks like he was a good acquisition to some people, and I applaud you for disabusing them of that notion before it continues to get out of hand.
I don't get it... Because MacD isn't playing 30 minutes a night on the top pairing, Berube is 'sheltering' him and that MacD is actually a terrible player?
Every player in the league has a role. Not everyone is a franchise defensemen, or a franchise forward. It's like criticizing a player for putting up the bulk of his points on the PP. Yeah - he might be better on the PP than at even strength, but if he can put up more points there than anybody else, then why not let him play there? Like I said - everyone has a place where they're most effective.
