Connor Carrick is an example of why I think the Capitals should kick the tires on a Bowey trade.
It's often said that defensemen take long to develop than forwards, and while I think that's mostly true I think that if a young D looks overwhelmed at the NHL level early they probably aren't going to have much of a career. Green, Carlson, Alzner, Orlov, Schmidt, and Djoos all showed some level of competency immediately in their first seasons in the NHL and I didn't really see that with Bowey last season or Carrick in his first season in Washington.
Give Bowey one more shot early this season, but if he doesn't show anything then I'd rather trade him while he still has value and promote someone like Siegenthaler, Johansen, or even Hobbs as the 6D if a spot is open and keep someone like Lewington or Ness as the 7D.
