Speaking at the team's press conference, Cassel informed the media that Kansas City Chiefs head coach Romeo Crennel never discussed removing Cassel from the game -- despite Cassel's poor performance.
Cassel was asked point blank by a reporter if Crennel talked to Cassel about making a change, and Cassel responded simply by saying, "No, he didn't."
To his credit, Cassel owned up to his mistakes on Sunday, blaming himself entirely for his one interception, on a pass intended for tight end Tony Moeaki.
"I have got to get him a better ball. Again, like I've said, it starts with me. I've got to do a better job of protecting the football and putting our team in a better situation to be successful."
Cassel also defended Dexter McCluster for his role in one of Cassel's three interceptions.
"Sometimes that happens in a game - when you throw a ball and it gets tipped up. Nobody is perfect. Dexter is a guy who has been very dependable and the ball just kind of came up in the air on that one."
Cassel completed just 24-of-42 passes for 251 yards, with two touchdown passes and three interceptions. Cassel was also sacked twice.
The Chiefs committed six turnovers in the loss to the Chargers, and Cassel is quite aware that the Chiefs must do a better job protecting the football going forward.
Turnovers have been killing us and I myself have to take better care of the ball. Obviously it starts with me. The whole team, I mean the whole offensive unit, just needs to do a better job of taking care of the ball. We talk about it. But we've obviously got to do a better job when it comes to game time.
Cassel will have to start performing better, as he could end up playing for his job -- sooner, rather than later.
