Romeo Crennel, the defensive coordinator on the Patriots' Super Bowl teams, agreed Wednesday to join the Chiefs in the same capacity, his agent said. Crennel, who was out of football this past season following hip surgery, will be reunited with Charlie Weis, who was the Patriots' offensive coordinator and agreed last week to take that job with the Chiefs.
Crennel will retain linebackers coach Gary Gibbs, the source told La Canfora, but other staff changes are coming. Defensive line coach Tim Krumrie was let go last week.
Crennel and Weis will join a franchise that has won just 10 games in three years and went 4-12 last year in Todd Haley's rocky first season as a head coach.
Crennel, 62, left New England to become the Cleveland Browns' head coach. And five years later, he was fired with a 24-40 record, including 4-12 in 2008.
Both men also face a big challenge to help Haley and Pioli get the Chiefs back into contention. Kansas City showed some life near the end of the season, but it hasn't won a playoff game since the 1993 season and is still just 6-35 in its last 41 games.
The Chiefs' defense had some of the worst games of any in the NFL this past season, twice sending opposing players into the record book with franchise-best performances.
Miles Austin, in an overtime victory over the Chiefs, set the Dallas Cowboys' single-game record with 250 receiving yards. Then, later in the season, in what many Chiefs fans consider the low point of the entire year, Cleveland Browns backup Jerome Harrison rushed for an astonishing 286 yards, wiping out Jim Brown's team record with the third-highest single-game total in NFL history.
The Chiefs pick fifth in the April draft. And they would seem to have a favorable schedule in 2010 with just three games against 2009 playoff teams.
