I know 6 pts from 8th looks like it is within reach but 6 spots is a helluva climb with 21 games left. Not impossible but probably not likely. It's not just going on a tear, you have to hope that the 5 teams above you (who are all trying to go hard to get in) all fail. Some statistician probably has it all figured out but if 93-94 pts is the goal for 8th and you're Anaheim, you'd have to go something like 15-4-2 or something close to that.
That's not going to stop them from trying. Their fanbase would be rightfully furious if they decided to become sellers at this stage.
