Uh, Scubadoo? Pittsburgh's GF-GA = -101. At 21 minutes a game, his share should be -33 or so (discounting power plays - see below). He's playing WELL above average for that team. Nobody who plays that much has a plus-minus so good. Tarnstrom, who leads the team in ice time, sports a -28. Lots of players with SIGNIFICANTLY less ice time have worse numbers. Drake's plus-minus, in context, is good.
(Using actual plus-minus numbers, PIT's a -422, which means that Drake, playing 1/3 of every game, should be a -28 or so - you can rough this out, and the numbers are about the same.)
Toronto's a +21 overall. Jackman's -11 came in only 29 games, averaging less than 20 minutes per contest. He was EASILY their worst defenseman, with BY FAR the worst plus-minus. You can say this another way - when Jackman was on the ice, Toronto tended to play very poorly, with respect to their average play this year. This is to contrast with Berehowsky - when he's been on the ice, Pittsburgh has played much better than they've tended to this year.
Now, the only thing you might say at this point is that the player who was EASILY Toronto's worst defenseman might still be better than one of Pittsburgh's best defenseman.
You might ...... but would you??? When Toronto's defensive corps is clearly not it's strength?
Come on, guys, plus-minus is an individual statistic that's contributed to by everyone else on the ice, including your goaltender. Of course, Berehowsky's play contributes to the overall team play, which has been woeful. But, the reality is, he hasn't been dragging the team down. A better player *might* have been doing more to bring them up, but Berehowsky can only do so much.
Pittsburgh is a WOEFUL team, with easily the worst goaltending in the league this year. Scubadoo, you think this *might* have contributed to his bad plus-minus?
This analysis ignores the power play, which a player may contribute to with no regard to his plus-minus, and which affects a team's overall GF-GA - the average NHL team scores as many PP goals as it allows, though, so this is a wash. Properly, you should still account for a *player's* contribution on the PP, though - a fact which makes Gonchar, for example, more valuable than his plus-minus (which still isn't all that bad).
You'd have to say that Berehowsky's worth more on the PP than Jackman, wouldn't you - even by a little bit? So, this is even MORE of an indicator that Drake's more valuable.
One more time: Jackman had a HIDEOUS plus-minus. Drake, not so hideous.
