Broncos CB Perrish Cox pleaded not guilty to a pair of sexual assault charges earlier this week and now has a trial set for Oct. 18. While the plea doesn't change much of Cox's case, we hear the trial date could be beneficial for the Broncos. The trial opens on the Tuesday following Denver's Week Six bye, which likely means the team will have the second-year corner for at least the first five games of the season. His presence could prove to be especially beneficial in ’11, as his experience in the league and chemistry with the team gives him a leg up on a potential undrafted rookie or a free agent who would need to be brought in to replace him. Cox has been able to keep his off-the-field issues from affecting his preparation, according to a source close to the team, and has had no problems staying focused. The one thing that might stop Cox from contributing to start the season is commissioner Roger Goodell, who could suspend Cox prior to the trial. In preparation of that, one daily team observer said he expects Nate Jones, who has split time between safety and cornerback, to concentrate solely on the CB position to provide depth.
