i count two (Dvorak line, Strome line)

You don't think Suzuki, Toffoli, Caufield is a Second Line?

Maybe I should have rephrased. I view these second lines as "Championship second lines". I don't think Toffoli-Suzuki-Caufield is a first line on the Leafs, Lightning, Bruins .... etc. But the other 2 are certainly second lines on those teams.

Suzuki line is middle of the pack 1st line in the league could be very good depending on the progression of Caufield.

The other two I'm not sure are exceptional 2nd lines, they are serviceable.

not sure i'd include leafs and championship in the same sentence but i do agree championship teams like tampa and boston did have better first lines. I think toffoli-suzuki-caufield arent far off though if suzuki and caufield can reach their full potential, i think its just a matter of time.

Toffoli last year had a 44 goal pace (give or take a few goals). Suzuki had around a 60 pt pace. Caufield had abt a 40 something point pace. So maybe, yes, it is a second line, but Suzuki & Toffoli are both, in my opinion, first line caliber, making it majorly a first line.
But yes, championship second line.

You would need Gallagher, Strome, And Drouin to all score at near their career highs to have the scoring out out of 3 second lines. Plus you would need Dvorak and Anderson to have career years (neither have ever paced for 50 points in 82 games) More likely you’re middle 6 is 2 high end 3rd lines/mediocre 2nd lines.

I would look at a 2nd line Having at least 2 players capabale of scoring 50 or 60 points regularly OR being very elite shutdown (like danault). But average 2 way 40 point guys won’t cut it I don’t think.

Toffoli, Suzuki, caufield is probably more of a low end 1st line assuming additional progression for both Suzuki and caufield and toffoli replicates last year
