David Akers has described his dip in form during the 2012 NFL season as a "head-scratcher".
The San Francisco 49ers kicker missed 13 field goal attempts during the regular season, and a 38-yard kick against the Atlanta Falcons in the NFC Championship game earlier this month.
The 38-year-old told CSN Bay Area: "I felt good all year, just doing the same thing in practice we've done all year. And wish those points would've counted in games. I had a great practice season, and training camp and pre-games. So it's one of those things.
"It's been a head-scratcher. But I'm still going to be positive about going into this game, 60 minutes away from possibility of being a world champion.
"You look at the kicks, it's so minute on how far they're off. We're talking inches on a lot of kicks. That's a frustrating thing because an inch is a mile in our game."
49ers head coach Jim Harbaugh has confirmed that he will be sticking with Akers as kicker during the Super Bowl against the Baltimore Ravens on Sunday.
