I guess you're right. That would make things much simpler. Then I would have to figure out whether some hybrid players are centers or wingers like Marleau. He played center for long time, but lately he has been playing wing on Thornton's line.
Both Marleau and Pavelski are natural centers, but played on Thornton's wing last year. So I guess it depends on whether you mean their natural position, or what they played as last year.
Is this a comparison for a career or just last season? If for a career, Hudler has been LW/RW and Filppula C/LW, most at center, but that LW is also ok. Filppula has been LW a lot at the playoffs, when games are tight and Babcock starts to use 3 lines.
Bertuzzi and Franzen also have been LWs during their career, at last season they played on the same line, and then Bertuzzi was on the left. I should put LW/RW for both.
At latest Red Wings Stanley Cup final runs 2008 and 2009 Franzen was a left winger. And I think at next season he will swap from right to left again (because Gustav Nyquist and Damien Brunner are right wings).
But thank god I didn't see either Datsyuk or Zetterberg at winger position anymore. Both are natural centers. They just have had some years other guy at wing before (Zetterberg more).
Nyquist is a natural center, and is "slotted" by most to take over either Bertuzzi's or Filppula's spot (depending on whether Filppula moves up).
Ilya Kovalchuk and James Neal both played mainly RW last season, but I would still consider them LWers. I would consider Burrows a RW, cause he mainly plays on the Sedins' line. I also think Higgins spent alot of time at RW the past couple seasons, I'm not sure though. I would still consider him a LW. I'm pretty sure Cole is mainly a RW too. Eriksson, Lupul, and Heatley also play at RW too, but didn't last season. Sharp, Jokinen, and Ennis also play C.
I would also consider Ryan, Franzen, Brown, Grabner all LW.
