I think the other problem with the Pens PP is it's really easy to predict where the pucks going to be moving. That a combination of being outworked.
I'd like to see something like this with our current line-up:
In this set-up- you've got Malkin on the half-boards, where he dominated when Crosby was absent last year. Crosby's down low, but not far from the slot where we can easily get a forehand shot off. Crosby and Wallace can criss-cross on the cycle and Whitney and Boucher hold the zone and maybe throw a wrister to the front of the net here and there. With a righty and the lefty criss-crossing with the puck behind the net you naturally have a lot of Kennedy turning shot opportunities (which we've seen Wallace try) and wrap-around opportunities. And Malkin can always skate into the slot and bang one home while the defense are trying to fish out Crosby.
But then Malkin can rotate to the point and suddenly you've got the old Yeo concoction- Whitney can sneak in that backdoor and be feed by Crosby from the half-wall, Malkin can fire the one timer, or Boucher can fire the one timer, with Wallace going hard to the net.
Wallace hasn't really scored, but he's a worker and a hard hitter. Also he gives you that right handed shot from the left for juicy rebounds for Malkin and Crosby to pounce on, and he adds the option of the through the blue-paint pass for an easy shot from Crosby or from him.
When Letang comes back he'd take Boucher's place, when Kennedy comes back he'd take Wallace's place. When Gonchar comes back he'd take Whitney's place.
