ALAMEDA -- Most NFL coaches prefer their bye week somewhere near the middle of the season. Raiders coach Dennis Allen said his team's bye comes at an ideal time, given there's so much work to be done. Allen said he and his coaching staff will spend an inordinate amount of time breaking down videotape from the first four games in an attempt to find answers to the Raiders' 1-3 start. "We've got a lot of work to do," Allen said Monday, one day after the Raiders lost to the Denver Broncos 37-6. "We've got a lot of areas that we've got to improve on. This bye week comes at a good time for us, gives us a chance as coaches to look at and evaluate what we're doing, who we're doing it with and come up with solutions that can help us get better and help us win some games."
