The 49ers looked oh so smooth out of the gate on Sunday night, defying inclement weather to take a quick 7-0 lead against the Colts at home. But they couldn’t weather Indianapolis for the duration of their prime-time matchup, with Jimmy Garoppolo and Co. slipping and sliding in the rain to the tune of four turnovers. On the flip side, Carson Wentz didn’t always look pretty, but with three total touchdowns, some gritty crunch-time runs and a couple doses of help from Jonathan Taylor and Michael Pittman Jr., he helped the Colts secure a much-needed 30-18 victory — the team’s third win in four weeks.
