It's official: San Francisco is legit.
Not only did the 49ers beat previously unbeaten Detroit; they won their third straight road game ... and they won it in the last two minutes. More importantly, they overcame a raft of stupid penalties to score the victory.
Once upon a time the 49ers didn't know how to close games. But they won in the fourth quarter in Cincinnati. They won in the fourth quarter in Philadelphia. And they just pulled another one out of the hat in Detroit.
Alex Smith will get credit for the win -- with his TD pass to Delanie Walker the difference -- but this one belonged to the 49ers' defense. It thwarted Detroit again and again, including the Lions' possession immediately after the Walker score when they couldn't pick up a first down.
San Francisco not only is the best team in the NFC West; it's becoming one of the best teams in the NFC.
