Browns coach Eric Mangini doesn't think he overworks his team. Cleveland running back Jamal Lewis said earlier in the week that he felt as though the coach asks for too much from his players in the week leading up to games. "I feel good about the way we practice, the time we practice," said Mangini. "Two hours of work on the field is a very reasonable time. The only time that practices are extended is if we don't execute something the right way."
