After all these years, there were never any slogans connecting the Denver D with D.J. and Dumervil. There never will be, either. The D in Denver's defense now stands for "different" after the Broncos on Monday released longtime linebacker D.J. Williams while contract talks with Elvis Dumervil may have reached a point of no return. Williams' release was expected after he fell out of favor in 2012 and had an overvalued $6 million salary due in 2013. A starting linebacker from the time the Broncos selected him out of Miami with the No. 17 overall pick in the 2004 draft until he was slapped with two suspensions that cost him the first nine games of last season, Williams is now part of an NFL free-agent pool that opens for business at 2 p.m. MDT on Tuesday. The Broncos have expressed interest in Pittsburgh running back Rashard Mendenhall, Jacksonville defensive tackle Terrance Knighton and possibly Philadelphia cornerback Dominique Rodgers-Cromartie, among other free-agent players. But they were also hoping to prevent Dumervil and their own defensive tackle Kevin Vickerson from entering free agency. With Dumervil, the contract squabble regards a pay cut. With Vickerson, the haggling is over a pay raise. What a difference a decimal point makes. Vickerson wants a bump from the $1.2 million salary he made last year. Dumervil has agreed to restructure, but not cut, the $12 million salary he is owed in 2013. His salary would become guaranteed by Saturday, so the Broncos want to work out a reduced rate before then. Broncos chief contract negotiator Mike Sullivan and Dumervil's agent Marty Magid resumed discussions Monday but got no closer to a resolution. Read more: Denver Broncos cut LB D.J.
