Rangers forward Brad Richards says he understands why he was dropped to the fourth line for Wednesday's Game 4 against the Kings. Richards played just over 13 minutes in New York's win on Wednesday after averaging about 18 minutes per outing for the first three games of the series, but the veteran center acknowledged coach Alain Vigneault's motives, saying "..you go try to win a game. When youre down 3-0 something has to change." Expect Richards to remain on the fourth unit when the series resumes in Los Angeles Friday.
