Desperate for some points, the 49ers completed four passes and got a 15-yard roughing penalty against Haloti Ngata, who later left with a knee injury. But again they couldn't cross the goal line, Paul Kruger got his second sack of the half on third down, forcing a second field goal by Akers, from 27 yards.
When Jones began the second half by sprinting up the middle virtually untouched — he is the second player with two TDs of 50 yards or more in a Super Bowl, tying Washington's Ricky Sanders in 1988 — the rout was on.
Then it wasn't.
"Everybody had their hand on this game," 49ers All-Pro linebacker Patrick Willis said. "We point the fingers at nobody. We win together and we lose together, and today we lost it."
