Olesz has better numbers over his career, and the Devils have been using Olesz on the PK a lot in the preseason. I don't think they'll go this route, but they definitely could.
No arguments. I just like having a couple real 4th line energy guys who are comfortable in different roles. If the Devils try to roll each line over 10 minutes, then maybe Olesz gets the spot, but if Debo wants to have 3 top lines and a 4th, Carter is more valuable IMHO.
