The Bengals and coach Marvin Lewis have hit a snag in their talks, according to a source. Lewis does not have a contract past this season. The two sides have met three times since Monday morning. After the first meeting, a new contract was expected. However, in subsequent meetings, the two sides could not come to an agreement on how the franchise should be run. On Monday, Lewis told owner Mike Brown what needs to change for him to consider staying in Cincinnati, where he's had two winning records in eight seasons.
