Yes, but its more than that.
1) Niners are great vs run which causes teams to give up on it.
2) Niners are usually WINNING which forces teams to pass more (and also improves the run numbers)
3) The Niners simply aren't the best in pass defense. Really good QBs have carved them up, but they are really good in the red-zone.
