Kyle Shanahan showed off his two-quarterback system in the San Francisco 49ers’ win over the Detroit Lions on Sunday. Jimmy Garoppolo got the start and finished with over 300 passing yards and a touchdown. Meanwhile, Trey Lance saw some action in the first quarter and his only pass was a touchdown. Marcellus Wiley explains why he trusts Shanahan even though he believes ‘it’s not really a 2-QB system.’
