What We Learned from 49ers’ win over Cardinals on Monday night

In front of nearly 80,000 fans in Mexico City — the majority of them rooting on the San Francisco 49ers — Jimmy Garoppolo led an offensive showcase.

Garoppolo had four touchdown passes as the Niners routed the Arizona Cardinals, 38-10, to pull into first place in the NFC West.

Receiver Brandon Aiyuk and tight end George Kittle had two TD catches apiece as the Niners soared, while the Cardinals fell to 1-1 with Colt McCoy starting in place of an injured Kyler Murray.
