Raiders general manager Mike Mayock has never worked in an NFL front office, but that's not the only thing he will have to get used to, at least according to an ex-NFL head coach.
"On a daily basis, he has to get used to the fact that Jon's gonna come into the office and motherf--k him," Brian Billick told Bleacher Report's Mike Tanier.
But Billick, a current NFL Network analyst who was a colleague of Mayock's while he was the outlet's draft expert, thinks Mayock will be able to hold his own in his relationship with Gruden.
