Sunday's meeting between the 7-4 San Francisco 49ers and 8-3 Miami Dolphins (4:05 p.m. ET, Levi's Stadium, Fox) will offer a heaping helping of familiarity.
The biggest storyline in this matchup centers on the student (Miami coach Mike McDaniel) facing the teacher (San Francisco coach Kyle Shanahan). Before leaving to become the Dolphins' head coach in February, McDaniel spent 14 years as one of Shanahan's most trusted assistants, with stops in Houston, Washington, Cleveland, Atlanta and San Francisco.
"We went through so much together," Shanahan said. "I think two years he coached receivers for me, but all the other times, he was a great position coach, but he was more valuable in the other way.
