The presence of good does not make the bad completely disappear out of existence.
Most people manifest the ability to understand object permanence by the time they are 2. A goal against is a goal against, and if my man Loligoski decides to make a poorly timed appearance, it is what it is. Pointing out a misplay is not a definitive statement about overall play. You may want to lighten up if you are interpreting it as such.
As for his overall play, our dear Goose has a whopping 5 secondary assists at even strength to go along with his 15th best ixG and one iHDCF, despite playing the 2nd most minutes this season. He's pretty far from driving the play. He's merely been alright overall, a thoroughly average middle pairing guy. But I guess all of those stunning positives mean you can't complain when he completely blows his coverage in front of the net.
