‘How the defensive assistants will shape up remained uncertain Wednesday night. The Bills and Steelers were waiting for a decision by Dick LeBeau. Both teams would like LeBeau as defensive coordinator. LeBeau was assistant head coach under Williams in 2003, but his contract is up. If LeBeau returns to the Bills, there will be no spot in Buffalo for defensive coordinator Jerry Gray. If LeBeau picks Pittsburgh, it’s uncertain what that will mean for Gray. Gray could become a candidate for one of the other open defensive coordinator positions in the NFL if the Bills let him out of his contract, which runs through 2004.’
