The Dallas Stars power play went from 18.2% (22nd in NHL) through November to 24.1% (8th in NHL) for the full season. That 6-point improvement is the difference between a fringe playoff team and a legitimate contender. Here is what changed.
The old setup (September-November): The Stars ran a 1-3-1 formation with the quarterback at the top of the umbrella. The issue: opposing penalty kills read the one-timer setup from the left circle and shaded their coverage accordingly. The Stars became predictable. Teams were blocking an average of 4.2 shots per power play in this formation. Source: Natural Stat Trick.
The adjustment (December): The coaching staff moved to a 1-2-2 (overload) formation. Instead of spreading across the entire zone, the Stars loaded the right side with three players, creating triangles and short passing lanes. The key changes:
- Bumper position moved to the right side: This created a new one-timer angle that opposing PKs had not prepared for.
- More cross-ice passes: The overload created wide-open shooting lanes on the weak side. Cross-ice one-timers are the hardest shots in hockey for goalies to save because they require lateral movement across the entire crease.
- Increased net-front traffic: The Stars placed a bigger body at the net-front who screens the goaltender and deflects shots. Deflection goals increased from 2 (Sept-Nov) to 11 (Dec-Mar).
The results:
- Shots per PP: Increased from 4.8 to 5.6
- Expected goals per PP: Increased from 0.42 to 0.61 per Natural Stat Trick
- Actual conversion: 18.2% to 24.1%
- Blocked shots per PP: Decreased from 4.2 to 2.9 (fewer predictable shot lanes)
Why it matters for the playoffs: Power play success in the playoffs is historically correlated with series wins. Teams with a top-10 PP advance past the first round 68% of the time since 2010. Source: NHL.com statistical database.

Deflection goals going from 2 to 11 shows the impact of net-front presence. Putting a big body in front of the goalie creates chaos. Rebounds, deflections, and screens all lead to goals.
