Jackson's dismissal comes just days after the hiring of general manager Reggie McKenzie, who appears determined to remake the organization.
Instant Debate: What now, Oakland?
When Redskins linebacker London Fletchervisited with NFL.com last week, he talked about NFL team captains being measured and legitimized by their grace under fire. When the floor falls out, players know what kind of captain they have. Young players watch their coach -- especially a new one -- with those same eyes.
When Jackson called out his players after their season-ending loss to the Chargers, telling reporters, "Yeah, I'm pissed at my team," whispers spread that he already had lost large sections of a locker room that once believed in his message.
Jackson admitted he was stunned by Tuesday's firing, especially when he considered himself close to McKenzie.
"He's going to gut this place," Jackson told Comcast SportsNet Bay Area. "He (McKenzie) wants to bring in his own guys. No job is safe right now."
One, however, is open in Oakland.
