Now the Raiders are hoping for a better working relationship between Gruden and Mayock, who was widely respected as a draft analyst since 2006 but now will be responsible for helping to make the picks.
Overall, the hiring of Mike Mayock is another piece to the "new leaf" that the Raiders are trying to turn over. Mayock will guide a team with about $80-million in cap space and 3 first round draft picks.
Despite having the GM title, Gruden is expected to be guy, who has the final say with the team on personnel matters.
The 60-year-old Philadelphia, Pennsylvania native will be serving in his first front office role with the Raiders in 2019.
In addition to the franchise's own first-round pick, the Raiders will have first-round picks from Chicago and Dallas.

"I've spent most of the last 15 years behind a microphone and I've got to be honest with you, I haven't been this nervous or this excited in that entire time frame", Mayock said. Mayock has plenty of college scouting experience, but he acknowledged he will need help in the day-to-day operations. "He'll prove his worth quickly". Star pass rusher Khalil Mack was traded to the Bears before the season for a package that included two first-round picks following a contract holdout, and receiver Amari Cooper was dealt during the season to the Cowboys for a 2019 first-rounder.
The Raiders finished 4-12, two years after going 12-4, though they did win three of their last seven games.
