I'm sure the Kings could get a pretty decent return for him from a team projected to go deep into the playoffs, but likely the future LD doesn't come from such a team. There is talk that NYR may be willing to part with a LD prospect, however, and Brown is from NY so maybe there is a match to be made there.
All the same, really hope he retires as a King and holds a position in the Organization thereafter. Seems like he's more focused on staying with the club / loyalty than chasing a cup with another team.
