Obviously Mika has a point- players don't like change and that probably makes it harder for him to find his game again. But you earn that deference- Gaborik was forced to play LW only when he went through cold streaks on the right.
But he has a problem- both Chytil and Trocheck have been substantially better of late. He's being paid to be a #1 and if he was doing that well, he wouldn't be seeing the reduction in ice time that he is.
So while the regular season is largely meaningless you have a conundrum. Do you try to get him back on track come what may, or continue to ride the hot hand? While it's still so early, I'd continue to do the latter.
