I think Kreider will figure it out, may not reflect in his point totals all that much which I don't think are all that bad, but his overall game, he needs to, just like the thread title says, do stuff.
Be engaged, skate, go to the net, hit.
I was watching a Duchene piece on NHL network and he talked out trying to play a perfect game way too much at the start of this season, once he let that go and started to just play with more instinct his season turned around.
Not saying Kreider is even close in talent level or on ice vision, but the way he looks on ice right now, he seems to be really over thinking everything out there.
