I don't see that happening this year or beyond. If Jagr moves on after this season, or goes down with an injury I would expect Eriksson to be the one to step into that role. Maybe if they move Morrow, and Cole can make the switch to LW, he might end up with Benn, but I just don't think it's likely. He's probably going to be on Roy's or Eakin's wing, and being on Roy's wing may hinge on Morrow's status after Whitney returns.
Could this Cole trade be foreshadowing Morrow's departure? Once Whitney returns, and he is skating so he's not far off, you'll have Morrow, Benn, Jagr, Whitney, Roy, Eriksson, and Cole all vying for spots in the top-six. And don't overlook all the kids who have been making their case for getting those minutes. In my opinion if Morrow hasn't been moved by the time Whtney comes back Cole is the odd man out, and likely plays with Eakin.
But even with that Cole could still hold some value. The Stars have been getting production up and down the lineup lately, and Eakin is a very good setup man. Cole may actually fare well with him, certainly not at the level he would in a top-six role, but not chopped liver either.
The days ahead in Big D look to be active and quite interesting. Maybe we'll finally see an identity for this team emerge.
