Whisenhunt dismisses three Cardinals assistants

Continuing to clear space for replacements, new Arizona Cardinals coach Ken Whisenhunt has released three assistants from the staff of former coach Dennis Green from their contracts, allowing them to pursue jobs elsewhere.

Freed from their deals with the Cardinals were linebackers coach Frank Bush, offensive line coach Steve Loney and wide receivers coach Mike Wilson.

Whisenhunt has hired five new assistants and continues to work on filling out his staff, a task he hopes to complete within the next week.

The addition of Russ Grimm as assistant head coach/offensive line on Tuesday made the much-respected Loney expendable. Credited with the improved performance of the Arizona offensive line over the second half of the 2006 season, Loney could end up on the Cleveland staff. The Browns have an opening after assistant head coach/offensive line Jeff Davidson left the team on Tuesday to become the Carolina Panthers' offensive coordinator.

Bush could soon join the Houston Texans' staff, possibly as assistant head coach/defense.

The Texans were denied permission to speak to Bush a year ago, when coach Gary Kubiak sought to hire him as defensive coordinator, and there have already been discussions between the two parties.

Whisenhunt continues to deliberate candidates for his two coordinator posts. There remains a strong chance that incumbent defensive coordinator Clancy Pendergast, an innovative schemer Cardinals player support, will remain in that role.
