The changes: : Brian Billick lost his job the day after the season ended. John Harbaugh, his replacement, assembled a top-flight teaching staff that included offensive coordinator Cam Cameron. He also retained defensive coordinator Rex Ryan, who probably is the best in the league at his job.
Eight of the Ravens' 10 draft picks this season - and 15 of 18 the past two years - are on the roster. Four already start, including quarterback Joe Flacco.
The comeback: : Relatively healthy on defense, the Ravens once again possess one of the league's most physical and effective units. The offensive line is young and learning, and Cameron has found a way to use almost everyone on offense. He even found a new running threat in fullback-tailback Le'Ron McClain.
