According to sources at ESPN, Vols assistants, defensive coordinator Justin Wilcox and linebackers coach Peter Sirmon, are leaving to join Steve Sarkisian's staff at Washington. Sarkisian gutted his defensive staff following a 67-56 loss to Baylor in last week's Valero Alamo Bowl. Defensive coordinator Nick Holt, linebackers coach Mike Cox and safeties coach Jeff Mills were fired after the Huskies allowed 777 total yards, the most in school history.
