SANTA CLARA -- Colin Kaepernick had a little, brief, microscopic shot to change everything about this 49ers quarterback "competition" on Friday in a single quarter of play.
He could've been brilliant against Green Bay. He could've upstaged presumptive starter Blaine Gabbert with a burst of dynamic passing and running.In what probably was his last and only chance before the regular season, Kaepernick could've emerged from his nine-month absence and grabbed a new hold of his old starting job.But that did not happen -- reality and rustiness interceded, and Kaepernick's unsteady second-quarter effort essentially sealed the deal, as the 49ers fell to the Packers, 21-10.
