Ravens running back Bernard Pierce has worked on a lot of things this offseason, including his speed and adding weight. He wants to improve on last year's positive rookie campaign when he ran for 532 yards and averaged 4.9 yards per carry, reports the Baltimore Sun.

"Of course, any category I was down on last year I'm looking to improve on that this year," Pierce said. "Everything last year was more of a memory game, a thinking game where I wasn't always reacting on instinct right away. Now, I'm just getting back in the flow of it. I've leaned down, and I'm definitely in shape."

Pierce took off once Jim Caldwell took over as offensive coordinator last year. During the seven games following Caldwell's promotion, including the playoffs, Pierce rushed for a total of 444 yards.

"I'm definitely proud of what I did," Pierce said. "I was able to help and contribute to that ring."

Although Pierce's workload is expected to increase this year after he averaged 6.75 carries per game as a rookie, the Ravens aren't planning to dramatically alter how they divide up the playing time. Ray Rice remains entrenched as the featured back.
