Petersen was hired December 6, 2013 - four days after Sarkisian accepted Pat Haden's offer.

UW ended up signing 24 players less than 2 months after Pete got hired.
A few stars and some really solid contributors, too: Budda, Sidney Jones, Pettis, Gaines, McGary, McIntosh, Sample, Jaylen Johnson.
Not bad for two months work by the new staff.
But what's interesting are the four guys who committed under the previous staff and whose scholarships were honored by Pete.
Jamie Bryant — Never played a snap
Matt James — Started first two games of 2015 while Strausser got Trey Adams ready; been anchored to the bench ever since
Drew Lewis — Never played a snap
Lavon Washington — Never played a snap
It's hard to overstate how much UW Football was cratering when Pat Haden threw us a lifeline and Pete accepted it.
