AP reports HC Mike Shanahan's long list of things he must address for the Denver Broncos to recover from their four-game losing streak grew by one very big item Monday when second-year CB Darrent Williams suggested some of his teammates don't believe their season is salvageable. "Some people are ready to hang it up, you know, you can tell," said Williams, who didn't name names. "And it's hard when you're losing. It makes everything hard, it makes coming to practice hard. It makes coaches harder on you. It just makes everything harder when you're losing. "So, a few guys are probably ready to hang it up. I don't know who. But I'm not." The Broncos (7-6) believe they must win their final three games to reach the playoffs. Yet Williams, who gave up several big plays in Denver's 48-20 loss at San Diego on Sunday, said that while nobody was outwardly conceding the season, he sensed some teammates were ready to cash it in. "You can kind of feel that it's just one of those seasons," Williams said. "... It can get hard right at this time, and it's easy to just say, 'I'm going to just play these three games and get an early vacation."' As possible evidence of his charges, Williams blamed the Broncos' four-game skid - only the second in Shanahan's 11 seasons - on some players taking some plays off. "Because," he suggested, "if we got 100 percent effort from everybody, we could easily win these games."
