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, Emmanuel Acho, and Mark Sanchez discuss whether they trust Shanahan's two-quarterback plan after the 49ers' win against the Lions. #SFY #NFL #49ers Download the free-to-play FOX Bet Super 6 app: https://foxs.pt/3z96p0j SUBSCRIBE to get all the latest content from Speak For Yourself: http://foxs.pt/SubscribeSPEAKFORYOURSELF The all-new FOX Sports App, built for the modern sports fan: https://tinyurl.com/y4uouolb ►Watch the latest content from Speak For Yourself: https://foxs.pt/LatestOnSFY ▶First Things First's YouTube channel: http://foxs.pt/SubscribeFIRSTTHINGSFIRST ►UNDISPUTED’s YouTube channel: http://foxs.pt/SubscribeUNDISPUTED ▶The Herd with Colin Cowherd’s YouTube channel: http://foxs.pt/SubscribeTHEHERD ►FOX Bet Live’s YouTube Channel: https://foxs.pt/SubscribeFOXBETLIVE ►Club Shay Shay’s YouTube Channel: http://foxs.pt/SubscribeCLUBSHAYSHAY ▶Titus & Tate's YouTube channel: http://foxs.pt/SubscribeTITUSANDTATE See more from Speak For Yourself: http://foxs.pt/SFYFoxSports Like Speak For Yourself on Facebook: http://foxs.pt/SFYFacebook Follow Speak For Yourself on Twitter: http://foxs.pt/SFYTwitter Follow Speak For Yourself on Instagram: http://foxs.pt/SFYInstagram About Speak For Yourself: Speak for Yourself is an hour and a half sports debate show starring our FS1 talent covering the day’s hottest topics in sports and offering their unfiltered takes.
