I posted some of this in the GDT earlier today, before I read this thread.
IMO, Dubi and Jenner are ok where they are for several reasons.
1. They are sloooowwwwlllllly turning the corner. Dubi moreso than Jenner. Jenner still squeezing the stick.
2. CBJ is in the #1 spot in the entire NHL - not that everyone can't be better, but they have 60 points in 39 games in part due to Jenner's and Dubi's play - and in part in spite of that play.
3. Repeat #2, but with a different angle. They are in the #1 spot because the other three lines have been above expectation, and because the PP has been hotter than hot. Moving either 17 or 38, if they are as off as some suggest, affects chemistry/performance of another line. I would not break up Gagner-Sedlak-Hartnell, and frankly the Anderson-Wild Bill-Calvert line, while in need of a few more scores, is playing lights out as well.
4. Noted in other posts - I don't see a 2nd line. I see 4 lines, identified by the players on that line, not a 1,2,3 & 4 (Saad-Wennberg-Foligno line is #1, but TOI difference for the lines is not that great at ES, just PP differential. Examples: Foligno high at 18:25, Cam at 17:53, Dubi at 17:35, Jenner at 15:19, Gagner at 13:35, Hartnell at 12:23 (NO PK at all), Sedlak low at 9:28 (but creeping upward). Moving players up or down, because of perceived line #, makes less sense than in the past.

Sure it would be fun to see Cam with more offensively talented linemates - but he gets that time on the PP. Cam has been incredibly effective at back-checking this year - so many more times than ever before I hear myself saying "NICE" as Cam sweeps back, intercepts a pass, back pass to puck moving D (OMG I typed that) and off they go. And I believe someone posted that Cam has 10 ES goals with those 2; not outstanding but SOLID.
If you move them, who ends up with 17 and 38? I don't see Gagner has effective with them as he's been, nor Anderson (although he's been off the scoresheet for a bit), nor Hartnell. I just see the lines fitting as is, for now. 2 losses followed by an OT win are not enough for line blender to resurrect itself. If the problems persist without improvement, that's different.
