Pass rush specialist R-Kal Truluck, an undrafted player who got his first break in the league last year under Robinson, said the coordinator took the hit because his players failed him.
"He worked hard to right the ship, which we all worked hard to do. He put his heart and soul into turning this thing around," Truluck said.
"But in the end it just didn't happen, and the unfortunate part is that the captain of the ship gave himself up. But we all were in it together, and we all have to take the blame together."
But Chiefs veteran free safety Jerome Woods, while acknowledging that his players let him down, said Robinson's read-and-react defensive philosophy didn't allow his players to be as aggressive as Woods though they could have been."
"I think any team -- whether on offense, defense or special teams -- takes on the attitude of the coordinator," said Woods, a prospective free agent who broke into the league under fiery former Chiefs coordinator Gunther Cunningham.
"When we walked into the meeting room with Gun, he was like 'We're gonna kill somebody this week!' With G (Robinson) it was like, 'We've got to do this or that.'
"All defensive players want to do is hit somebody and hurt somebody," Woods added. "But when you're sitting back reading and reacting and thinking, it takes away from your ability to do that.
"There were times when it was like we didn't know what to do. I don't know if we were getting out-coached or out-schemed or what, but there were times when we fell behind and it seemed like we were searching for something that could work."
Defensive end Vonnie Holliday, who will be back with the Chiefs next year, defended Robinson's approach.
"It was not from a lack of passion or effort that we couldn't get this fixed," said defensive end Vonnie Holliday.
"We knew what kind of guy G-Rob was. You saw it today when he stood in there (at a press conference) and said all the things he did. But in this business, sometimes things just don't work out, and you make you changes and go out and find ways to get it done."
QUOTE TO NOTE:
"Greg (Robinson) and this defensive staff and our players did everything we possibly could to make it work, but it wasn't getting done. Now we have to go to another level on defense if we are ever going to be what we have to be." -- Coach Dick Vermeil on the loss of his defensive coordinator.
