Portland ML seems pretty good for Sunday

They lost in what I guess was a desperation game for Houston.
Now Portland has to be thinking they can not have this series evened up at 2 heading back to Houston for GM 5...Portland needs this game just as much as Houston now.
What am I missing here? The spread is only -2??? Don't get it.

I think this game ends up deciding the series. We shall see. I got a hunch Houston wins. Hope I'm wrong. This looks like a 7 gamer.
