All the underlined is wrong. Both have seen their pp time drop, their roles dropped and been demoted to other lines. Both have spent time on the 3rd line or are currently on the 3rd line.
Thanks for the clarification. However, I think if you double check that you'll find Wilson, and especially Smith, have not in fact seen a diminished role thru the season. Oh sure, there was a game Smith saw some pine in the 2nd period (or was it the 3rd?) if they were truly played according to the "line rushes" order posted by followers on twitter, then I guess we could pretend that they've been "demoted" to the 3rd line. But the practice and pre-game line orders have rarely matched up with how they're deployed come game time...

I'm just not seeing any sort of significant drop in ice time at es or on the power-play between the two prior seasons and this one when they are on the so-called "3rd line". Sure, they've dropped a rank among forwards, but at es that accounts simply for the push up of Jarnkrok filling into the top 6 during all the injuries and the recent addition of Johansen. As for the powerplay (where they again have dropped a rank due Johansen) there's still a huge diff between 7th place Wilson at 2:14 avg/game and the 8th place guy Jarnkrok with his 0:50.
