What Lewis needs to do is develop a core of citizen-cops in the locker room, and have them police it. Does anyone really think Corey Dillon took Emily Post lessons upon signing with New England?
Nope. He went to a place with a carefully constructed core of Good People, who let him know what was OK and what wasn't. Because they were talented and had Super Bowl rings, Dillon listened. The Bengals have a few good men - Willie Anderson, Reggie Kelly, Carson Palmer, to name three - but they do not have that culture of business-like responsibility all good teams need.
Until they get it, this stuff will happen and the Bengals will keep underachieving. If you want to lean on Lewis, point to that.
I disagree with Daugherty that everyone just needs to get over it. After all, if it's so unreasonable to expect professional football players to behave within the constraints of the law, then why don't the other 31 teams have nine players arrested in nine months?
That being said, if Lewis is going to insist on bringing in players with issues, then he needs to heed Daughterty's advice and "carefully construct a core of Good People". Thing is, there's not enough room on an NFL roster for a carefully constructed core large enough to deal with the issues this team has.
