Meier needs to be in Bratt's spot on the right side as a shooting option on the PP. I'd like to see Mercer replace Bratt or even Palat could be a better fit. You improve PP2 as well.
I think Meier definitely deserves another look at the half boards shooting position after a strong showing the other night. But Bratt has also been good there most of the season, one-timing seam passes from Hughes into the net. Maybe put him in that spot on PP2.
As you suggested, that would mean we put Mercer or Palat in as the bumper on PP1 (with the other guy as the bumper on PP2), and I think that could work. Both of them have the hand-eye coordination to look for tips and deflections, the high motor to win puck battles for rebounds, and the hands to distribute the puck well with one-touch passes.
