With a 0-5 record, are the Bills starting to improve from the look of last Sundays game?

On October 10th, 2010 the Buffalo Bills undergone another horrible and close lost against the Jaguars. Unfortunately they couldn't strive for their first win. With a bye week this week, what do you think the Bills need to work on the most to achieve and strive for a win on October 24th, 2010 against the Ravens?
