Anquan Boldin indispensable to 49ers’ success

Anquan Boldin, the face of the 49ers' frustration the last time the team played at Levi's Stadium, was the face of determination Sunday against the Ravens.Boldin, whose frustration was visible against Green Bay on Oct. 4, made arguably the biggest play of the game in the fourth quarter against the Ravens.Boldin, who had eight catches for 107 yards and a touchdown against the Giants in the previous game, had five catches for 102 yards Sunday.[...] the numbers were eerily close to what Boldin put up against the 49ers in the Super Bowl when he played for the Ravens:Boldin said the 49ers knew from watching video that they could exploit the Ravens' banged-up secondary."We wanted to take advantage of that," he said.Head coach Jim Tomsula said a Baltimore player had fallen on Boldin's leg and it tightened.Whatever the case, the 49ers took him out for the final offensive series.In critical times, I feel like the team looks to me as one of the guys that needs to make a play.
