Smith's final stat line (24-of-35, 204 yards, one TD, one INT) was mediocre, but it was his turnovers and lack of red-zone execution that really made this a poor performance.
In his first trip to the red zone, Smith had Randy Moss open in the end zone but simply overthrew him, and the 49ers settled for a field goal. In his second trip, Smith decided to tuck it and run on 3rd-and-3, and he came up short.
With under three minutes to go in the game, Smith had a chance to at least get the 49ers within a score, but he was intercepted by Josh Robinson.
Smith added a fumble in Minnesota territory a minute later, sealing San Francisco's first loss of the season.
To recap, even with two gift turnovers from Minnesota late in the game, Smith could not lead the 49ers into the end zone in five fourth-quarter possessions.
His performance against Minnesota, however, wasn't his worst.
