IMO Gillis is trying to build a bottom six with speed, skill and two way play. When we had a fourth line that included "fighters" (Hordichuk and Rypien) it was a horrible experience that was dominated territorially and contributed zero offensively. Fuck me, that Hordichuk/Johnson/Rypien line was brutal. The current fourth line is miles ahead of that one.
I think if Rypien or Hordichuk had a chance to play with a decent centre they wouldn't look nearly as bad as they did when they played with Ryan Johnson. I wouldn't have played both of those two guys on the same line in the playoffs but if you had a guy like Lapierre playing with a Hordichuk and a guy like say Taylor Pyatt.... that could be a decent - good 4th line.
Some targets MG would hopefully look at that are upcoming UFAs are Taylor Pyatt, Jordin Tootoo, Travis Moen or even George Parros.
A 4th line of Lappy, Moen and Tootoo would be a real solid line come post season.
