I don’t have experience in playing hockey like many here. My sport was basketball & I equate a good Powerplay like an efficient motion offense in basketball.
Teams with a great motion O move the ball around the umbrella looking for an opening, many times using skip/crosscourt passes to catch defenders off guard & getting them out of position, in order to create that weakness to exploit. In the paint, there’s always someone ready for a putback, if needed. Players on the strong side & weak side, both, are always moving, brushing off defenders to create space for themselves.
Someone that stands around dribbling the ball, with no real movement allows the defenders to dictate what is available to the offense, instead of the other way around.
I see our players the vast majority of the time just “dribbling the ball” around with no real definitive/decisive cross ice passing causing those needed defensive breakdowns. If the defense & their goalie aren’t having to move much & you don’t have a Pasta or Ovi that can put it wherever, whenever they want, you just aren’t going to be consistently good at the Powerplay.
When we’ve moved the puck quickly around & across the ice successfully, the results are obvious.
Thanks for coming to my Ted Talk.
