I think so.
I was just browsing around the roster of the niners and it hit me, that we have a new center, who came from the New Orleans Saints. I'm curious as to how much help he has provided to Fangio and the defense in terms of knowing the tendencies, counts, and audible plays that Drew Brees might get into during the game. Also, being the anchor for the Saints the last couple of years, I think he would have a lot of information about the blocking schemes.
All of this is speculative, but since the playoffs are do-or-die, I wouldn't put it past our guys to squeeze every bit of information we can, to gain a tactical advantage.
