Overhaul on Oregon's staff?

The worst-kept secret in sports the past month or so has been Oregon's plan to promote offensive coordinator Mark Helfrich to head coach if Chip Kelly left for the NFL. Multiple sources are saying that will formally be announced today, including Rob Moseley of the Eugene Register-Guard and Aaron Fentress of The Oregonian. The question remains, though, how much other turnover there will be on the Ducks' staff.
