49ers officially announce Mike McDaniel and DeMeco Ryans as coordinators

The 49ers coaching staff has undergone a bit of upheaval since defensive coordinator Robert Saleh left the team.
The 49ers have officially promoted Mike McDaniel and DeMeco Ryans to offensive and defensive coordinator positions respectively.
McDaniel has been an assistant on staffs with Kyle Shanahan since 2011 when he joined him in Washington.
Ryans has received rave reviews on the defensive staff and seemed destined for a defensive coordinator job in the near future
