My take is that it's because we finally have 2 NHL players playing on the 3rd line.If something works it works. We haven't had enough bottom 6 scoring this year. Finally now Cuylle, Brodzinski and Kakko seem to be creating some chemistry together and knocking in some goals the last few games. They all bring something different to the line and if they can keep it going that's great.
I believe Brodzinski is just a guy (just an AHL guy at that)... and can easily be upgraded.
Our lack of 3rd line scoring depth was directly related to playing a 3rd line of non NHL players + a rookie.
