It is a long season. At some point, there is bound to be a pothole or two in the road for the 49ers. But after four games, coach Kyle Shanahan's team has been the NFL's most consistent outfit. In a league known for its week-to-week nature, the 49ers essentially have been the same team in every game they have played. They have cruised to victories by scores of 30-7, 30-23, 30-12 and 35-16.
