‘Mularkey, 42, will take just one Steelers assistant with him, quarterbacks coach Tom Clements, who will become offensive coordinator of the Bills. Mularkey, however, won’t wait until next fall to compete against Steelers coach Bill Cowher. Their teams will meet in Buffalo next season, but he and Cowher both want to hire LeBeau as their defensive coordinator and, as of last night, there was no word on who would get him. LeBeau was assistant head coach last year in Buffalo and was secondary coach on Cowher’s first staff and later promoted to defensive coordinator. Cowher interviewed Bears defensive coordinator Greg Blache at the team’s headquarters yesterday and could hire him if he loses out on LeBeau.’
