BEREA, Ohio -- Cleveland Browns coach Eric Mangini must have felt like he was at home in his living room scolding his three young sons.
For the second consecutive Monday, the Browns coach stood in front of his players and lectured them about their Sunday sins.
Too many penalties. Too many turnovers. Too many mistakes.
Too this. Too that.
"They're tired of me saying it, and I'm tired of saying it," an exasperated Mangini said. "We can't have penalties. We can't. We can't turn the ball over. We can't do it. We'll drill it, we'll talk about it, we'll review it, we'll analyze it. ... You can't expect to win close games.
"Two games decided by five points with big swings in momentum, you can't do it."
For the second game in a row, the Browns' starting quarterback -- this time, it was backup Seneca Wallace filling in for injured starter Jake Delhomme -- threw a costly interception. For the second game in a row, the Browns failed to score in the second half as their offense disappeared. For the second game in a row, Cleveland's defense played well enough to win.
"We were leading both games," wide receiver Mohamed Massaquoi said, slightly shaking his head. "We turned the ball over. We had too many penalties in the second half. We just didn't finish the way we're supposed to."
Although there's no evidence team president Mike Holmgren is ready to make any drastic moves, the Browns have no breaks in their schedule during the next seven weeks, and without a win or two or any significant improvement, the cries for Mangini's dismissal already filling the air on sports-talk shows will get louder.
"We know we're a better team, and we just handed out victories," cornerback Eric Wright said. "We were in situations where we should have won two games, and we lost them."
Mangini's post-mortem on Cleveland's latest loss, which dropped the Browns to 1-11 in home openers since 1999, focused on the team's self-inflicted wounds (nine penalties for 78 yards) and the offense's inability to move the ball in the second half.
With Wallace making his 15th career start, Cleveland gained only 55 yards and three first downs -- one came on a penalty -- after halftime. The Browns were predictable and unable to find any holes in the Chiefs' defense, which ended last season as the NFL's 30th-ranked unit and had a short week after playing Monday night.
After reviewing tape, Mangini said he wished he had used more of the "Wildcat" package with wide receiver Joshua Cribbs at quarterback and Wallace lined up on the edge. The Browns used it only once, with Cribbs picking up 1 yard on a third-and-3.
"Looking back, it's something I would have done more in retrospect," said Mangini, adding offensive coordinator Brian Daboll concurred with his assessment. "We talked about it this morning. Both of us agreed: We should've run it more -- to get Josh more touches. He's got a chance on any play."
"Everybody knows that Josh can do once he has the ball in his hands," Massaquoi said. "Special things happen when he has the ball."
Mangini did not have any update on Delhomme, who injured his right ankle while throwing an interception in the Week 1 game at Tampa Bay. Delhomme was in a walking boot on the sideline Sunday. Mangini promised he would have further information Wednesday, when the Browns begin preparing for this week's game in Baltimore.
Mangini did not promise any wholesale lineup changes, but he made it clear that he won't tolerate mistakes from those currently on the field.
"I don't really see it as me benching anybody," he said. "I see it as either hold onto ball and get carries or you don't hold onto the ball and you don't get carries. The same thing with penalties. Either you stay onsides or you don't. If you jump offsides on third down, then we're not going to play you on third down. That's it. We'll put somebody else in, and if they beat us on the play, they beat us on the play.
"If that person's maybe not exactly who we would want on that play, it's going to be better than giving away a first down. We've got to do it. There's no alternative."
