SANTA CLARA -- Quarterback Colin Kaepernick is coming off one of the low points since taking over as the 49ers starter in the middle of the 2012.
A solemn Kaepernick stood in front of the media on Wednesday -- nearly a week removed from his two-interception showing in the 49ers’ 19-3 loss to the Seattle Seahawks.
“Everyone has their own way of working their way through things,” Roman said. “The beauty of Colin is he’s his own harshest critic. And when we have a rough game as an offense, he usually comes back out swinging for the fence, and pretty dialed in.
“He’s a very competitive guy. He wants to win, and that’s his ultimate goal as a football player. He wants to win. When we fall short of that, he takes that tough. He’s a competitive guy. He’s out there laying it out on the line.”
Kaepernick has a chance to get on track Sunday against the one-win Raiders, whose defense ranks 15th in the league.
Kaepernick has fallen to No. 20 in the NFL with an 87.8 passer rating for an offense than ranks 22nd in total yards and tied for 25 in points scored.
