‘The front office thinks highly of New England’s offensive coordinator Charlie Weis. Both he and Patriots defensive coordinator Romeo Crennel are considered head-coaching candidates this winter. However, if the Bills want to interview either of them, they must do it by Friday or wait until after the Pats are knocked out of the playoffs. Neither Weis or Crennel have major head-coaching experience. Other highly regarded assistants include St. Louis defensive chief Lovie Smith and Pittsburgh offensive chief Mike Mularkey. Neither has been a head coach.’
