Fifth-round pick RB Chris Rainey is something of a wildcard in the backfield, joining five other tailbacks, counting Rashard Mendenhall, who is coming off ACL surgery. Rainey's 4.4 speed in the 40-yard dash has him in the mix to contribute any number of ways. "I'm learning the
playbook, just out here to grind, do my job, and find out how to fit in," Rainey said.
