SANTA CLARA — Nothing establishes a defense like a hard-hitting safety, roaming the deep middle and clocking any opponent who ventures into the area unaware.
As they prepare for Saturday's NFC divisional playoff game against the Green Bay Packers, the 49ers don't have one of those guys. They have two. Free safety Dashon Goldson and strong safety Donte Whitner, while overshadowed by the likes of tackle machine Patrick Willis and sack hoarder Aldon Smith, form a punishing one-two punch in the San Francisco secondary.
"The physical presence that those two guys bring at the back end, it's amazing," 49ers cornerback Tarell Brown said. "It helps this team, and it also brings an identity to this defense."
Brown should know. He not only has witnessed plenty of big hits by his safeties. He was on the receiving end of one of them, when Goldson missed the Giants' Hakeem Nicks and inadvertently plastered Brown on a pass late in the third quarter of last year's NFC championship game. Brown suffered a concussion.
More frequently, the 49ers safeties limit their damage to the opposition.
Goldson's victims include Tampa Bay's Mike Williams and Cleveland's Greg Little in 2011, and Arizona's Early Doucet in Week 8 of this season; some called the hit on Doucet, which separated the wide receiver from the ball (and very nearly his molars) the hardest of 2012.
