[Kansas City.com] Romeo Crennel again said Monday that Matt Cassel will be the starting quarterback for the Chiefs when they play Baltimore on Sunday at Arrowhead Stadium.

But Crennel also left open the possibility that backup Brady Quinn could play against the Ravens. Crennel said the Chiefs might give Quinn some of the starter’s work in practice this week.

Crennel also laid out in general terms what it might take for him to bench Cassel and replace him with Quinn.
“At some point, as a coach, you go through and you see what’s happening in the game and how a guy is reacting and how he’s responding to what’s happening in the game,” Crennel said. “If you feel he’s inept, constantly making poor decisions, bad choices, then that’s when you move on from him and give someone else a chance.”

Cassel has committed 10 turnovers in the Chiefs’ four games. Projected over a 16-game season, that’s a staggering 40 turnovers from their quarterback.

Cassel is fifth from the bottom in the NFL in passer rating. He’s better only than rookies Branden Weeden of Cleveland and Ryan Tannehill of Miami and struggling veterans Mark Sanchez of the Jets and Jay Cutler of Chicago.
