After a decade of mostly familiar names, Super Bowl XLVII is set to provide some welcome new blood under center. Sunday will mark the first title game in five years to feature two quarterbacks who’ve never been here before, but that’s about where their similarities in experience end. For Colin Kaepernick, this start in New Orleans comes barely three months after the first of his NFL career. For Joe Flacco, it’s the next step in his playoff success. But even with all the pressure young Kaepernick is set to face, in my mind, and in terms of scheme, support, and circumstance, there will be more of it placed on Flacco.

Like the 49ers, previous versions of these Ravens relied on a bruising running game and great defense to buttress a young quarterback as he improved from week-to-week. This year, those areas of strength have lagged. After a long stretch of dominance, Baltimore's famed and historic defense fell to the middle of the pack in nearly every category, and although the Ray Rice–led running game is still formidable, its efficiency and production took a step back.

This means that for the first time, the Ravens have become Joe Flacco’s team, and more than ever, Baltimore has relied on its passing attack. Ray Rice has been a steady bailout option for most of Flacco’s career, but it’s Torrey Smith, Anquan Boldin, and Dennis Pitta who will be the keys come Sunday night.

The Trenches NFL Podcast: Robert Mays and Ephraim Salaam

By Robert Mays at 5:33 PM ET

This week's podcast started with mixed emotions. For as much joy as I had for Ephraim attending his good friend Chester Pitts's wedding, it just wasn't the same without him in the studio. Colors just seemed less bright, ya know?

We powered through though, and after asking what the vibe was like in Houston following Monday's loss, we talked some J.J. Watt, Vince Wilfork, the uniquely developed games of the league's young pass rushers, and the dearly departed Cam Cameron. But mostly, we talked about the Dirty Bird. Inspired by this week's great touchdown celebrations, I asked Ephraim about his all-time favorites, totally forgetting his time with the famed 1998 Falcons. You'll hear the heartbreak in my voice when I learn he never Dirty Bird–ed — mostly because that means there's no video.
