There were rumblings and 'sources' coming out Vegas when Brady was made part owner of the team, the current coaches have 'packed it in' in terms of doing anything of showing a pulse. They know they are gonna get fired after this season, so that means Rob Ryan, Patrick Graham, Marvin Lewis, are just riding it out til the season ends as they know their fate already. Pretty much collecting pay checks.
At 2-7, they fired their OC/QB coach/Offensive Line coach which was not a surprise really. The OC is straight out of tier 3 college division, the offensive line is trash as they cannot run nor pass protect, the QB coach ain't helping either the starter or the back up.
As for Antonio Pierce, he may survive this season or not depending on their record finish.
All of this falls on Mark Davis, ever since Al Davis passed away he's been totally inept on the football side of things.
