Personally, If both Ray Allen and Paul Pierce were in the NBA 3-point contest then you'd have to hope that either of those two guys wins it so the Boston Celtics have more insurance that they are the best-shooting team in the league right now.
I'm not saying that it would be impossible for one of the other competitors to win the contest, however if our two best shooters were in the NBA 3-point contest it would certainly be nice if a Boston Celtic was able to win the 3-point contest two seasons in a row...
