The entire OL, WR group, TE group, LB's and DB's sans Brown and Jones were on the team in 2014.
The only guys that are brand new are Dak, Elliott and a handful of DL, so yea, the inexperience thing is fairly overblown aside from Dak just because of the critical nature of his position.
I'm not worried about Elliott at all, he's a big game player who is used to elevating his game when the competition is highest.
As an aside, I am looking forward to Sean Lee playing in this game. He missed 2014.
