The San Francisco 49ers have had some well documented woes with their receiving corps this season.

Michael Crabtree — the team’s 2012 leading receiver –tore his Achilles tendon last spring and only recently became healthy enough to play.

Anquan Boldin came in and quickly became Colin Kaepernick’s No. 1 target, leading the team in receptions (70), targets (112) and receiving yards (958) in 2013.

Kyle Williams became the No. 2 target to begin the season – not including tight end Vernon Davis – but was released over a month ago after more fumble woes and after catching just 12 passes for 113 yards in nine games.

Mario Manningham has only been healthy enough to play in six games, and has largely disappeared since Crabtree’s return three weeks ago. After catching 8 passes for 83 yards in the first three after he came back, Manningham has caught just one pass for 2 yards in the previous trifecta.

The list goes on…

Well, despite all the injuries and various issues that have accumulated throughout the season, the passing game has seen an upswing in recent weeks.
