Most of the running duties were shared between rookies Bernard Pierce and Bobby Rainey, but which one of them performed well enough to get the upper hand as the No. 2 back next to Ray Rice?
After Thursday's 48-17 win vs. the Jacksonville Jaguars, the jury is likely still out with both presenting contrasting styles. The Ravens also threw the ball 48 times, with 36 pass attempts by starter Joe Flacco.
Pierce ran 10 times for 35 yards. Rainey only had seven yards on two carries as both averaged just 3.5 yards per carry. Neither scored a rushing touchdown, though coach John Harbaugh was satisfied with the effort.
The Ravens moved up in the draft to select Pierce in the third round. Pierce has dealt with hamstring injuries during training camp.
"Pierce was physical. He had been talking about his hamstring a lot to me, and then he jumped over that guy. So I don't want to hear anything more from the hamstring," Harbaugh said with a laugh. "The hamstring talk is finished."
Rice already is sold on Pierce.
"One thing I know is that when I come out the coaches want to feel confident about who we put in," he said. "You don't draft a guy that high to sit on the sidelines."
Rainey was undrafted, but showed why he's likely a lock to make this roster. His pass catching ability out of the backfield is where he shined and has the edge on Pierce.
Rainey ran a wheel route out and caught a pass from Flacco over the top on third down-and-three. It was a 17-yard gain that put the Ravens on Jacksonville's 12 and led to the first touchdown by the first unit since the preseason opener vs. the Atlanta Falcons.
In the fourth quarter, Rainey caught a pass near the line of scrimmage from backup Tyrod Taylor and took it 48 yards for a touchdown.
"I'm coming in with a chip on my shoulder, definitely," Rainey said about being an undrafted free agent.
