It's also a testament to the icetime they get on the PP. I mean, there have been potent PP combinations in junior hockey before. But I don't really recall a situation where the coach pretty much flat out says he's trying to run up the stats for his top players, and a guy like Schremp typically plays the full 2 mins of every powerplay, probably gets over 20 PP mins some nights the way they're calling things in the OHL this year. The 5 forward group (Schremp, Bolland, Hunter, Perry, Kostitsyn) have 119 PP goals. Schremp 34G, 54A on the PP?
Anyway, I wouldn't try to deflect the credit onto Hunter or Bolland. Neither of them are particularly "special" offensive junior players, IMO. Hunter does his job well, working the corner and sending the puck out, Bolland moves up and down from the left point to the backdoor spot by the net, and while they do those jobs well enough, it's not as if dozens of other players in junior couldn't do the same thing. Schremp does have the most "magic" of the bunch on the PP, IMHO. (Bolland brings other elements away from the PP, some tenacity and PK recklessness that makes him at least as valuable overall... but not nec. on the PP).
I guess if I was trying to deflect any of the credit for Schremp's PP numbers, I'd deflect them to Hunter... Dale, that is. The whole coaching strategy of building a team around a PP, of piling the minutes onto his stars, throwing caution to the wind, playing ES with a particular eye to drawing more PP time... that's what gives Schremp the opportunity. It's chicken and egg, though.
