The first drive was a win for the San Francisco 49ers. The 49ers defense stopped the Kansas City Chiefs vaunted offense on a three-and-out, and the 49ers offense responded by getting into field goal range and taking a 3-0 lead.
The Chiefs took over the rest of the quarter on a long drive that took up the rest of the time. Chiefs quarterback Patrick Mahomes rushed it in on an option play to make the score 7-3 to Kansas City. This is how the quarter would end.
Unfortunately, the bad side of the gunslinger mentality that Jimmy Garoppolo has shown up to start the second quarter.
