I'm going to say it yet again this year.
The Rangers need to move Derek Stepan.
He's not a #2 center and he's terrible on the PP. Why they put him out there with the #1 unit is beyond me. He has no speed. Not strong on the puck. He doesn't possess good hands. He doesn't move the puck quickly.
I haven't figured out what they should target coming back but I'd settle for picks for now.
