They've had Laughton on the block, but with a lot of young players added to the roster the last couple years, they wanted a critical mass of the "right" veterans to guide them (not TDA!).
But at this point, it's time for players like TK and Sanheim to step into leadership roles.
It's harder for other players at this point, b/c they haven't solidified their role as core players yet.
Moving Laughton to 4LW makes him expendable b/c he's easily replaced by Richard or Lycksell in that role. Problem is they don't have someone else who can move to center in case of injury.
So the timing may depend on the progress of Gaucher and Rizzo in LHV. If they're confident one of them can fill in for a stretch, they'll be more willing to move Laughton at the TDL, otherwise they may wait until June.
