"He's impressed me for sure," Nyquist said. "A really smart player. I think that's kind of what's impressed me the most, how smart he is out there. He creates space for himself in a really smart way. For being maybe not the biggest guy, maybe not the strongest guy, he still holds onto the puck and kind of seems like he's got some extra time out there. Be tight on him, finish your checks and stay on the right side."
Despite missing 11 games with various injuries, Pettersson leads the Canucks in goals with 22 and in points with 42.
Pettersson scored Vancouver's first goal in Detroit on Nov. 6, a game the Wings eventually won in a shootout, 3-2.
"You got to stay above him and make it hard for him," Larkin said. "He's a player that is very aware of everyone on the ice and he doesn't like the physical play, so when we get a chance we got to finish our checks on him and make it a tough night for him."
Pettersson, 20, is 6-foot-2 but just 176 pounds.
