At least one Bucs assistant coach may be jumping ship.

Running backs coach Art Valero has had discussions with the St. Louis Rams about joining their revamped staff under head coach Scott Linehan.

Nothing has been finalized, but it's likely Valero would coach the Rams' offensive line. St. Louis fired offensive line coach Paul Boudreau last week and Greg Olson was informed he would not be the team's offensive coordinator in 2008.

Valero worked with Linehan twice in his career - at the University of Idaho from 1991-93 and at Louisville from '99-'01. During those stops, Valero served as offensive coordinator and assistant head coach.

Valero has spent six seasons with the Bucs, all under coach Jon Gruden. He coached tight ends for two seasons and the last four years has coached running backs. In 2006 and '07, Valero also held the title of assistant head coach.

The Bucs have informed coach Richard Mann they would like to sign him to a contract extension. Speculation is that offensive line coach Bill Muir might be headed to Miami to be reunited with Bill Parcells, the Dolphins new executive vice president of football operations.

The Bucs have expressed an interest in hiring former Nebraska coach Bill Callahan, who spent four years on Gruden's staff in Oakland before becoming the Raiders head coach in 2002-03. Callahan coaches the offensive line.

The coaching carousel is just beginning to spin.
