On preparing for this 49ers team:
Just a lot of differences. Obviously there's some different players, it's quite a bit different of a scheme. There's a handful of guys left over, but a lot of fresh, young talent. And a lot of hungry guys, you can tell. So it's quite a bit different group.
On use of safeties being similar to what Cardinals do:
Yea, there's a lot of similarities, not stuff that our defense is doing currently, but a lot of stuff we saw during training camp, day in and day out.
