For the team, I don't think it's a distraction at all (unless he's talked to certain people about going to SF with him (ie other coaches) or maybe if they want to go with him to SF), but this could be a distraction for the man himself. I don't think anyone on the outside could possibly know how much or how little that it is effecting him.
Though from my extremely limited understanding of how they run things is he sits down and finds players to target and how to best destroy the weakest links.... which I don't think will be that hard to do on this Packers defense right now... at least not in the passing game, running game might be a bit tougher. So I don't think that this distracting for him will have much impact because the flaws are fairly clear, the execution of the plays and maybe the play calling at high pressure moments are the only real hard parts...
like the Cowboys play caller fell into the NFL play caller trap on the final drive, of wanting to pass the ball too much in this pass happy league instead of keeping it balanced or sticking with what got you there (running the ball)...
That could happen to the Falcons, but it's less likely since they're much better at the passing game and being balanced.
