Regardless of if he's on Thornton's, Couture's, or Hertl's wing, he's not going to be the guy expected to drive possession. Also, on any line he would be on he wouldn't be the guy expected to do the heavy lifting, as we've already got top notch players that do that. (Thornton, Pavelski, Couture, Donskoi, Hertl, etc.) He will purely be a complementary piece here. I think he will do just fine with the reduced responsibilities and weaker comp he'll face than he did in either AZ or CO.
Plus, our 2nd PP unit is looking pretty damn scary: Boedker, Hertl, Donskoi, Schlemko and one of Vlasic/Meier/Goldobin/Ward. That's a #1PP unit for a lot of teams.
