Anquan Boldin's Updated 2013 Fantasy Outlook After Week 4

San Francisco 49ers wide receiver Anquan Boldin went flat after a monster debut with his new 2013 team, but he picked his production back up in Week 4 on Thursday night.

Boldin had a 42-yard catch and then followed it up with a 20-yard touchdown catch from quarterback Colin Kaepernick to push the Niners ahead of the St. Louis Rams by a score of 7-3.

Joe Flacco, who benefited from Boldin's beastliness en route to a Super Bowl MVP award, can attest to how beneficial it is to chuck it to the supremely physical receiver in adverse times:

There aren't any other dependable options in San Francisco's receiving corps, which otherwise consists of rookie Quinton Patton, the diminutive Kyle Williams, Marlon Moore, Chris Harper and apparent first-round bust Jonathan Baldwin.

Jerry Rice, San Francisco legend and best receiver of all-time, even chimed in to give Boldin props:

The Niners' passing game has been a disappointment in terms of fantasy, but Boldin should continue producing at least at a No. 2-caliber level.

St. Louis' secondary is formidable, with a feisty cornerback tandem of Cortland Finnegan and Janoris Jenkins.

For Boldin to produce 62 yards and a touchdown on just two catches in the first half is a substantial achievement, especially on the road, against an NFC West rival and with the season on the line.

Boldin finished with 90 yards on five receptions on seven targets in the 35-11 win, proving that he's more in tune with Kaepernick, which should bode well for the remainder of 2013.
