The San Francisco 49ers kicked off the free-agency period with the signing of four-time All-Pro receiver Randy Moss. Moss, who did not play last season, had arguably the worst season of his career in 2010. Playing for the New England Patriots, Minnesota Vikings and Tennessee Titans, Moss totaled 28 receptions for 393 yards and five touchdowns. With a year off to recover and refocus, he’ll look to get a fresh start with Jim Harbaugh and the Niners. Signed to only a one-year, $2.5 million deal, Moss gives the team a big-play target who presents low-risk and high reward.

Apparently adding Moss was not enough, as the Niners signed former New York Giants receiver Mario Manningham to a two-year deal on March 18. Manningham may have been the Giants’ No. 3 receiver, but he played a key role in helping them win their second championship in four years. Although he had a subpar regular season, his play improved during the playoffs. In both the NFC Championship game and the Super Bowl, Manningham demonstrated that he is capable of making clutch plays- which is exactly what the Niners need in converting third downs (ranked 31st overall).

By adding Moss and Manningham to the roster, the offense can now stretch the field effectively. Their speed brings another dimension to the offense that it did not have last season. With Vernon Davis and Delanie Walker running short and intermediate routes, opposing defenses must cover all parts of the field.

Now that Peyton Manning has officially joined the Denver Broncos, the Niners will turn back to Alex Smith. With Smith returning, he will have more receiving options to choose from compared to last year. Last season, Smith threw for a career-high 3,144 passing yards while recording his best quarterback rating (90.7) in his first year under Harbaugh. He has shown steady improvement, and with Moss and Manningham at his disposal, Smith could be even better next season. Couple the signings with a full offseason to understand the offensive system, the sky’s the limit for him.

On defense, bringing back Carlos Rogers and Ahmad Brooks was crucial. Rogers had the best season of his career last year, as he was tied for a team-high six interceptions while making his first Pro-Bowl and All-Pro team. Brooks solidifies the pass rush long-term playing opposite of Aldon Smith. One of the potential concerns that the Niners face is the possible loss of Larry Grant, who received an original-round tender from the team. Last season, he showed that he was a starting-caliber linebacker when he filled in for Patrick Willis, who missed four games in December. With these signings in place, the Niners should once again be a top-10 defense in 2012.

Overall, San Francisco has done a solid job of addressing their needs. If the players live up to expectations and work together, there’s no reason why the Niners can’t make another deep run in the playoffs.
