The Golden State Warriors are well aware that even the lowliest opponents are salivating at the chance to knock them off, and they got another reminder in the opener to a three-game trip. After Harrison Barnes bailed them out, the Warriors will try for a better performance Sunday night against the New York Knicks. Golden State (43-4) blew a 24-point lead in the second half Saturday against league-worst Philadelphia and looked like it might head to overtime until Barnes hit a 3-pointer from the corner with 0.2 seconds left in a 108-105 victory.
