I would love to move Kesler back to the 2nd PP unit once he comes back (and move Garrison there as well). Kassian has looked good with the Sedins so far.
It would give us two pretty darn good PP units.
Sedin - Sedin - Kassian
Edler - Bieksa/Hamhuis?
Booth - Kesler - Raymond/Schroeder
Garrison - Raymond/Schroeder?
Once the PP is done, send out Burrows/Higgins - Lapierre - Hansen.
I've been saying this for a while, but I don't really like Booth on the PP, I think Burrows is a better option, or a red-hot Raymond if he continues his success. I do agree with moving Kesler to the 2nd unit though, but I think keep Garrison on the first because the Sedins will give him way more opportunities than a Kesler-based unit for his big slapper (which I hope to see in the near future).
To just expand on what you have already done...
Sedin Sedin Kassian
Edler Garrison
Raymond/Burrows Kesler Raymond/Schroeder
Bieksa Hamhuis
maybe move Ballard onto the second unit if he continues his play, but that is just a thought
One thing that I've noticed, is that either Garrison is being told to roam around and not utilize his shot, he doesn't have faith in his shot, or (and this is the one I think) is that Edler is not setting him up well enough, could be a rust thing but I've seen Edler only give passes to Garrison that can't be one-timered. If this is the case and it can't be solved easily, then Hamhuis with Edler and Bieksa with Garrison could be a good idea.
