Michael Crabtree had his best season as a pro.
Michael Crabtree emerged as the 49ers' elite wide receiver. He had his best season with 85 catches for 1,105 yards and nine touchdowns.
What made these numbers even more outstanding was that Crabtree really had little help from the other wide receivers on the team.
Once again, wide receiver is a major weakness of the 49ers. After Crabtree, the remaining options are very questionable. Mario Manningham, who was starting opposite Crabtree, tore two knee ligaments and there is no certainty how he will return from his very serious injury.
In 12 games, Manningham had 42 receptions for 449 yards and one touchdown. His injury could be career-threatening, as Manningham relies on his speed.
The third receiver, Kyle Williams, has never been able to stay healthy. This was also a problem in his college days at Arizona State.
Williams played in 11 games this year, before he went out with yet another injury. He was not that productive with only 14 receptions for 212 yards and one touchdown. It may be time for the 49ers to go with a more reliable player that does not have such a history of injury.
Randy Moss was a disappointment. He is a free agent and the 49ers probably will not retain him. Moss was supposed to give the 49ers a much-needed deep threat, but he had trouble gaining separation from the better defensive backs in the league.
In the regular season, Moss only had 28 receptions for 484 yards and three touchdowns. His playoff performance will be remembered for the pass that Moss made no attempt to catch in traffic. Kaepernick's throw was high but Moss made no effort, which enabled Ed Reed to make the interception.
The 49ers tried to upgrade the position by using their first selection in the 2012 draft on a wide receiver, A.J. Jenkins. Unfortunately, Jenkins made no impact, as he did not catch a pass all season and was rarely even active for the games.
It's too early to call Jenkins a bust, but he is heading in that direction. If he can become a productive player, it would be a huge lift to the receiving corps.
The 49ers should try to sign a proven wide receiver in the free-agent market. The rookies coming into the league may not be ready to contribute right away, so a proven veteran would be a good investment.
