5 Teams That Should Worry San Francisco 49ers

The San Francisco 49ers have a must win game against the Houston Texans in Week 5 at Candlestick Park. Win, lose or draw the 49ers still have a tough schedule ahead of them. At the beginning of the season, San Francisco was the best team on paper and was an odds on favorite to return to the Super Bowl. They still have a chance to get to the playoffs and get to the Super Bowl, but the team still has concerns with poor performance, play calling, injuries and off the field issues with All-Pro linebacker Aldon Smith.

Though it is still early in the season certain players and holes on the team are clear and need to be managed if not rectified. The play-calling needs to be run heavy with short passes to running backs then some intermediate and deep throws down the field.

The defense is still without Smith and will be missing him for another few weeks. Nose tackle Ian Williams is out for the season, and linebacker Patrick Willis is nursing an injury. The offense puts the defense in binds when they do not run the ball effectively. It is apparent that quarterback Colin Kaepernick needs to manage the football game until he can improve his touch passes and accuracy.

If they beat the Texans, it would be just a start to playing up to that elite level. The 49ers have five teams they need to be aware of after they face Houston.

The Falcons may have some big injuries, but they are still formidable. By the time the 49ers face them, however, some of those players will be healthy.
