After a whirlwind few days of negotiations and flirtations, New England Patriots offensive coordinator Charlie Weis -- the man most responsible for the development of quarterback Tom Brady -- has elected to remain with the Super Bowl XXXVI champions.

Sources confirmed for ESPN.com that Weis and the Patriots have reached agreement on a two-year contract worth about $1 million. The deal is expected to make him one of the league's highest-paid coordinators.

Weis, 45, became a hot coaching commodity toward the end of the regular season and his value escalated dramatically in the playoffs.

Weis fielded an offer from the Carolina Panthers, where close friend John Fox is new head coach, but rejected a deal said to be for three years at $500,000 annually. The Tampa Bay Buccaneers also wanted to discuss their offensive coordinator vacancy with Weis, but he told club officials he was only interested in the team's head coach position.

Several prominent league sources told ESPN.com on Wednesday night that the Buccaneers and Ravens defensive coordinator Marvin Lewis could have an agreement in principle completed as early as Thursday for Lewis to become Tampa Bay's head coach.

On the Patriots' charter flight back to Boston on Monday after winning the Super Bowl, Belichick and New England owner Bob Kraft emphasized to Weis how much they wanted him to stay. They also reviewed the parameters of a contract proposal that Weis' agent, Craig Kelly, had presented to the team.

Weis did a brilliant job in 2001 of designing game plans that, while limiting Brady's choices in the passing game, still provided him enough options to win.

A 12-year NFL veteran, Weis began his career with the New York Giants and Bill Parcells in 1990 as a defensive and special teams assistant. He was then the team's running backs coach for two seasons (1991-92) and followed Parcells to the Patriots for four seasons (1993-96). He went with Parcells to the New York Jets for three years (1997-99), then to the Patriots in 2000.

It is believed the Panthers are now talking to longtime NFL offensive assistant Dan Henning about their coordinator position. Carolina also might turn to New York Giants tight ends coach Mike Pope for its offensive coordinator job. Pope interviewed with Fox last week.

The Panthers also have to hire assistants to coach their quarterbacks and tight ends. Former Buffalo offensive coordinator Mike Sheppard is believed to be under consideration for the quarterbacks job.
