The current Western Conference standings provide a study for how fleeting success is in the NHL and how quickly teams on the bottom can rise toward the top.
There are pros, like the Winnipeg Jets' defense and puck possession, which can be looked at as one in the same. There are cons, like the Dallas Stars' defense and puck possession, to the point where they have allowed the most goals in the NHL.
The Calgary Flames have found ways to win, particularly with six third-period comeback victories. That's a pro. The Minnesota Wild have been weighed down by their struggling power play, a con all season long.
