Why does Brady not come through the one time they need him to throw a touchdown?

Why is it that the one time that the Pats need Tom Brady to throw a winning touchdown he doesnt come through but then people call him clutch when all he does is let his kicker win the game, if you really think about it if they didnt have the greatest clutch kicker then they wouldnt have hit the field goals and no body would be talking about how Tom Brady is so great because he would only have one super bowl ring
