The Boston Marathon tragedy deserves its own discussion.
I would expect that there is a strong likelihood that it will result in a ripple affect throughout sports. I would not be surprised in any way if this tragedy forces a delay in the resolution of the Sonics/Kings situation. If so it is the right thing to do. While we all hate to be left twisting in the wind there is no doubt that the league's first obligation is to protect the safety of its fans and if necessary they should appropriately prioritize security going into the NBA Playoffs.
Prayers and best wishes to all those affected.
