I don't know what numbers and analytics Harbaugh is talking about, but I disagree and think it was the wrong call and you take the gimme field goal with all that time left in the game. If you insist on going for it and sweeping left, you use a speedy back like Dixon and not a north/south runner like West. It is deflating for an offense, which isn't very good to begin with, to come away with zero points in that situation. Let's not confuse "being aggressive" with poor decision making.
