Former 49ers offensive coordinator Mike McDaniel will return to San Francisco on Sunday to face his old team. The quick turnaround he's overseen in Miami—along with the leap taken by Tua Tagovailoa—has been one of the biggest stories in the NFL this season.
Now, the Dolphins face one of their toughest challenges of the year on a field where the 49ers have been tough to beat. San Francisco is 4-1 at Levi’s Stadium with their only loss to the Chiefs. The Niners carry a four-game winning streak into Week 13 and stand atop the NFC West.
