Marrone begins constructing staff

Doug Marrone is not a man who wastes time. After just two days on the job as the Bills Head Coach, he has already started putting together his staff.

Multiple reports have Mike Pettine joining Marrone as his defensive coordinator, and Nate Hackett following Marrone to Buffalo as offensive coordinator.

Pettine guided a Jets defense that finished among the top eight in the NFL in each of his four seasons with the team. Prior to his stint in New York, Pettine worked as a linebackers coach in Baltimore.

In a press conference earlier this week, Jets Head Coach Rex Ryan said he hoped Pettine would steer clear of his division rival.

"We had the conversations, and Mike thinks it's best that he go to a different team as defensive coordinator, and I wish him all the best unless he goes to Buffalo," said Ryan.

As for Hackett, the 33-year old has very little NFL experience. He served as the Offensive Quality Control Coach for two years in Buffalo in 2008 and 2009, after holding the same job with Tampa Bay.

With Syracuse, he took concepts from Buffalo's old "K-Gun" offense with Jim Kelly and incorporated them into the Orange attack.

The Bills have not confirmed either hire.
