No problem. I'm happy to answer any more specific questions you have.
His use on the PP in Edmonton should be broken into pre-rebuild and post-rebuild days. Post-rebuild, the PP started to be formed more around Hall, Eberle, Nuge, etc., which makes sense. In that scenario, Hemsky was bumped to the 2nd unit and really fell off. Not due to lack of ability, but just because the Oilers started to pursue a different route. Nuge became the main puck handler, Eberle took Hemsky's spot on the LW boards, and the focus became more on the younger players.
Pre-rebuild, he was the main driver on our first unit. He set up on the LW boards and was the main distributor of the puck. Usually, there'd be someone in front of the net, specifically Smyth or Penner, and there'd be someone on the RW boards that would sneak down back-door and try to open up the cross-ice pass. Oddly enough, that guy was usually Horcoff, although he was also famous for whiffing on Hemsky's passes. The guy can really thread the needle through PKers. The left defender would stay open for a pass from Hemsky in case things went south, and the right defender was usually a left shot also trying to get open for a one-timer. During our 2006 run, we also ran an umbrella with Hemsky still at the LW and Pronger at the top as the left shot looking for a one-timer. In essence though, the PP revolved around Hemsky maintaining possession, one player screening the goalie, and the other players looking to open themselves up for a pass, either as puck support or to look for a shot.
He'd also periodically peel off the boards and shoot it himself. He scored quite a few goals that way, and his shot was good enough that defenders usually backed off of him once he had solid possession, which opened up passing lanes a lot more. Hemsky was also generally the guy to carry the puck over the blue line with possession, something that he's really good at with his hands and speed. Really good at.
