Who will have the biggest impact on D in the Super Bowl?

I think Raji has the best opportunity to with Powncey out(no way there's a 75% chance like he says with that ankle) and 2 other Olinemen out. There's so many great defensive players in this game. There's Clay Mathews, Raji, Trevon Williams, Charles Woodson, Troy Polumalu, James Harrison, Cacy Hampton, Lawerence Timmons, and a lot of other play makers. What do yall think?
