They generate about 85-90% (eye test/gut feel) of their shots on the PP on the 1 timer quick passes to the forwards from the hashmarks, (Brock, Petey/Miller), and netfront (Bo).
The deep man is always looking to one time pass to Bo or Brock, so that leaves only Bo or Quinn setting up Petey. It's very predictable what's happening, because the shots are coming from 3 parts of the same zone on the ice.
The way I would remedy this is go oldschool play with two guys who bomb the puck from the line, and have 2 guys who roam the front for 1 timers, tips, and screens. The bottom guy's job is back of the net puck retrieval, and secondary screens.
2 real D on the backend on powerplay is oldschool I know, but it fixes some of the problems which the team has, which mostly stem from the fact that Quinn has to walk the whole line. Put another D on the right side who can absolutely rip it. Petey and Brock on the hashmarks, and Bo doing deep man duty. 4 shots is better than 3, with increased defensive posture. PP2 uses two D, aye? Go back to it on PP1 too.
