The 49ers are in their first Super Bowl for 18 seasons, one year after losing out in the NFC Championship game to the New York Giants.
The defensive end told reporters: "It's kind of like someone is pulling the rug out from underneath you. You're like, 'We were so close.' We came up short [last season], and we're back here. We just have to go take care of business now.
"To be back in the NFC Championship game, I don't think our team took it as much for granted how hard it is to get there. Getting to the Super Bowl, now especially, you have to take advantage of it.
"The talent level, what the coaches have been able to get out of us, it just all has come together. This roster is loaded."
The 49ers face the Baltimore Ravens in New Orleans on Sunday.
