I think I read an article by Boyle where he talks about static stretching decreasing muscle function by 10%. In the article he said if you take an elite NBA athlete who can jump 30" vertical and he loses 3 inches but is able to move better with less likelihood of injury he would rather do static stretching before a game or event.
