I've rerun this play about a dozen times, and I have to say that I am incredibly impressed with Doug Baldwin on this play. He could have EASILY gone up for the ball and attempted to catch it as well, but somehow (in a split second) realized that it was Kearse's ball to catch and ducked under him to give him a shot at the ball. Look at how close and how easily Baldwin could have also gone up for the ball, and it's mind-boggling that he made that decision as quick as he did.
Kudos to Doug, and obviously to Kearse for his utter concentration on that one.
