Dolphins owner Stephen Ross wants an aggressive, creative offense next season. That unit won't have quarterbacks coach David Lee, the man who brought the Wildcat scheme to the team, then the NFL. Lee accepted the University of Mississippi's offensive coordinator job, the school announced Monday. He will take over play-calling duties from coach Houston Nutt, with whom Lee worked at Arkansas. Lee's Dolphins tenure produced mixed results. Miami's quarterback play was often spotty, but he was credited with bringing the Wildcat, a formation that features a running back who takes a direct snap, to the NFL in 2008. Many NFL teams now employ the scheme.
