ST. LOUIS -- The San Francisco 49ers obviously wanted to send the rest of the NFC a message as they make their final preparations for Week 4: We are still a team to be reckoned with at the quarter point of the season.Make no mistake, the 49ers, particularly on offense, are not perfect four games into their NFC title defense. However, they emphatically showed Thursday night that they are not ready to remove themselves from playoff consideration.
