NEW ORLEANS -- Defensive tackle Justin Smith did not provide the 49ers with the same game-altering presence in the playoffs after returning from a late-season injury.
Smith had his worst game of the season in Super Bowl XLVII, according to Pro Football Focus, which rates every player's performance in every game.
Smith returned to action in the postseason after sustaining a partially torn left triceps tendon on Dec 16 against the New England Patriots. Smith had only two quarterback hurries in three postseason games.
He played 59 of the 49ers' 71 defensive plays on Sunday against the Ravens. According to PFF, Smith had negative grades for run defense and pass-rushing in the 49ers' 34-31 loss to the Baltimore Ravens on Sunday.
Smith recorded just three tackles with no quarterback sacks, hits or hurries against the Ravens. He lined up primarily against Baltimore rookie left guard Kelechi Osemele, who had a career-best grade against Smith.
Here are some other Super Bowl notes from PFF:
--Quarterback Colin Kaepernick, who had a career-high 302 yards passing, had the second-highest grade of his season. When targeting Michael Crabtree, his passer rating was 122.5. His ratings for his other targets: Vernon Davis 116.7, Delanie Walker 114.6, Randy Moss 30.0. He did not attempt any passes to a running back.
--Running back Frank Gore had 110 yards on 19 carries, but he gained just 21 yards on eight rushing attempts in the A-gaps (between the center and guards), according to PFF.
--Center Jonathan Goodwin tied his worst grade of the season, as he struggled in run-blocking and allowed a quarterback hit and two hurries.
-Left tackle Joe Staley had the best grade of any offensive lineman with a a clean pass-blocking sheet for the second straight game.
--Nearly half of Crabtree's receiving yards (54 of 109) came after the catch.
--Vernon Davis had six catches on eight targets for 104 yards. He caught all three passes for 54 yards when Ravens linebacker Ray Lewis was in coverage. Lewis and safety Bernard Pollard had the worst grades on the Baltimore defense.
--Defensive tackle Ray McDonald was the 49ers' most productive lineman with one sack and four hurries.
--Linebacker Patrick Willis matched his season-best grade as he recorded six tackles and allowed only one catch in coverage for 8 yards.
--Third cornerback Chris Culliver allowed just four catches while being targeted nine times. But those four catches went for 123 yards and a touchdown. He also got flagged for pass interference on a third-down play. (Coach Jim Harbaugh said afterward he thought it was a bad call.)
--Safety Donte Whitner allowed five catches for 57 yards and two touchdowns among the six passes that came his way.
--Cornerback Tarell Brown had a solid game. he allowed three catches in five targets for just 29 yards.
