I talked about this with you yesterday with Hall too I believe. But using a players stats relative to his teammates when his team is garbage and than trying to compare him to good players on good teams is worthless. Of course RNH has great relative stats compared to the rest of the team. The majority of his career he's played with centers like Horcoff/Gagner/Belanger/Gordon.
So how would you explain Kopitar. And your reasoning is a bit of a stretch. Being players on better teams also have better players with them on ice at same time, and then yes better players on ice without them on
RNH had bad line mates with him and without him
So for example, Kings GF with Kopitar could be 60% and without him 52%. Oilers could be 50% with RNH and 42% without him. Both have similar impacts
Your theory is only right if good player on good team is played with bad linemates, and then good teammates are played when hes not on ice. however this is nearly never the answer. Like for example if Kopitars most common linemate is NOT Doughty, and then Doughty plays majority of game away from Kopitar. Which doesnt happen, best players play with best players on top lines. Kopitars most common line mates are Doughty, Muzzin and Lucic
