Mike Preston's final report card for 2011 season

There wasn't much improvement in Joe Flacco from a year ago, but he was more accurate in the second half of the season compared to the first because the Ravens ran the ball more. Flacco had a lot of passes dropped, but he still has to improve his pocket awareness and ball security. He was solid in one playoff game, and very good in the other. He completed 312 of 542 passes for 3,610 yards and 20 touchdowns. (Al Bello, Getty Images)
