I love what A Train brought but I dont think he is all that great of a D man. If you put a stunt man in pads and tell him to block shots and hit, he would probably do it.
He always got turned around on his off side, he gets beat wide all the time because he is a lefty playing the right side, he's not all that fast, he has no offense, and honestly, he isnt that smart of a player. There are way better options then A Train for way less money and honestly, ya, I think Phillips could turn Gryba into a better and more versitile player then A Train. Hell, I think if Lee ever grabs a set he can be a better player then A Train to, that's a HUGE IF though.
Kuba, well you need to replace his offense and if The Sens go out and get a guy like Michalek, I bet you the D looks like this.
Karlsson/Phillips
Michalek/Cowen or Wiercoich
Carkner/Campoli
Lee
if it's Capbell
Gryba/Phillips
Karlsson/Campbell
Carkner/Campoli
Lee
I honestly think A Train leaving will help The Sens more then it will hurt it going forward. One dimensional players are worth very little IMO and they are interchangable in the long run, especially when Chris Phillips is your partner.
