I don't mind the bottom line's thing being that they are fast and hit stuff, whilst being a bit rubbish doing anything else. It gives Lindy a tool to wield.
That said, the third line feels a bit like the spare-part line. Krebs and Greenway are closer to fourth liners than decent third liners. And Zucker is fine but doesn't have a thing he does particularly well.
I'd rather have Benson - Cozens - Quinn be our defensively responsible wild card third line, and then have Skinner and two other players as our second line.
