The Broncos honored murdered cornerback Darrent Williams yesterday, opening the Boys and Girls Club teen center in Montbello that carries his name.  Williams was 24 when he died in a drive-by shooting at Eleventh and Speer Boulevard on New Year’s Day last year.  Police have yet to arrest a suspect.  Mother Rosalind Williams told the crowd she’s not done working in her son’s memory  –  she plans similar projects all over the country that will help “stop the violence.”  A week ago, a larger-than-life statue of Williams went up in front of the club.  It’s a place where kids can do homework, play sports, or just hang out.
