There already is "the Most Outstanding Player" of the year award, it's called the Ted Lindsay Award (previously Lester B. Pearson). It is voted on by the players - as it should be. That is McDavid's award to win.
Oilers are going to miss the playoffs by 15pts or more, so the argument for MVP is that if it weren't for McDavid you'd miss the playoffs by 30pts or more? What??! Who gives a crap. You're missing the playoffs either way.
There's long been NHL precedent that to be MVP you have to be part of a playoff team. The closest someone came to winning the Hart & not have his team in the playoffs was Jarome Iginla in 2002 & he still lost to Theodore because Theodore got the Habs to the playoffs (in an extremely close vote tho).
There are way too many candidates this year to put McDavid as one of the top 3, but if he does get a nomination that's as far as it should go.
MacKinnon, Kopitar, Hall, Kucherov, Malkin & even Rinne have all had outstanding years that have helped propel their teams to the top of the standings or into playoff positions.
Giroux & Bergeron have had fantastic seasons too.
McDavid has had a great second half & he'll likely get the Ted Lindsay for it & the Art Ross, but someone else should get the Hart.
