The team I would not want to play the most is the NY Giants. They have beaten us 2 times in a row, and I hope we don't have to face them in the playoffs. Other teams that concern me: Seattle, Green Bay, and Atlanta.
Seattle doesn't scare me as much when they have to travel to Candlestick, but I don't like playing division games in the playoffs. In my thinking, even bad division teams (St Louis this year is an example) can surprise you, since they know you so well. So while I would expect the 49ers to win, I would prefer not to face them.
I still remember the Green Bay from last year, and while they are a shadow of their former self, and have plenty of injuries, they have been winning a lot of games lately. I would prefer to not face Rodgers.
Atlanta doesn't scare me, but this would a game on the road for the 49ers, in a loud dome. I would prefer to have home field advantage throughout the playoffs.
