SANTA CLARA, Calif. (AP) For coach Kyle Shanahan and the 49ers, this season has been about rebuilding for the future. But the process has suddenly been accelerated by the arrival of their new starting quarterback.

Jimmy Garoppolo starred in the team’s first road win of the year, a 15-14 victory at Chicago. He completed 26 of 37 passes for 293 yards, throwing for the most yardage ever by a San Francisco QB in his first start, and led a 14-play drive that set up a winning field goal with four seconds remaining.

“(We) went in not really sure how it would be, but I think it went a lot better than expected,” Shanahan said Monday.
