SANTA CLARA (AP) — Colin Kaepernick showed flashes of the quarterback he used to be in his first start in nearly a year. He used his athleticism to turn a possible safety into a 10-yard run , connected on a deep touchdown pass to Torrey Smith and scrambled when he had no open receivers for a 29-yard gain. But far too often in Sunday’s 45-16 loss at Buffalo, Kaepernick looked more like the quarterback who lost his starting job a year ago to Blaine Gabbert than the one who went to a Super Bowl and NFC title game in his first two years as starter.
