There shouldn't have been much concern about the San Francisco 49ers after a 2-3 start to the season. They were clearly still one of the best teams in football, despite a few losses.
It's not entirely perfect for the 49ers yet, and injuries have a lot to do with that. But don't believe that San Francisco has lost much.
The 49ers had a dominant first half against the Seattle Seahawks, let the Seahawks back in the game for a bit in the second half, and ultimately slammed the door shut and beat their NFC West rival yet again.
